产品责任制为设计带来的启示

产品使用的舒适性不是根据设计者、制造商或者零售商自身的需求作为设计标准的,而是根据使用者的需要进行设计的。

Juan等人就将以下内容作为主要舒适性能的判断参数

—产品设计质量

—产品的适用性

—特定性能

—适用领域的服务性

设计质量是在指在一项设计中所针对的三个分别独立的步骤:

(1)满足使用舒适性的构成要素;

(2)产品或服务的设计观念的选择,需要满足使用者对必要功能的需要;

(3) 如果可以严格执行将已确定的产品设计观念融入到一系列具体的设计规范中这一理念,那么就会满足使用者的需求。

Juran将四个和使用舒适性相关的使用参数以及它们彼此的关系进行了归纳总结,正如表一所示。而所设计产品的好坏会受到市场调查效果的影响。产品的好坏

的标准可能是很模糊的,而对于设计师或者是一个设计团队而言就有必要将不完整的市场信息列出一个设计理念框架进行研究。市场上对生产设施的可用性和它们的承载能力的了解是必不可少的,因为对这一过程的了解和生产息息相关。但工人们都有这种必要的技能吗?什么样的材料可用而它们的成本是多少?是否是人们依据预期的售价对成本估计过高?许多工程材料的可靠性和可维护性的基本性能还没确定,因此备件的应急使用能力对许多产品可能是至关重要的。而产品适用领域的服务性也同样具有重要意义。

严格的产品责任的落实

这些因素影响了使用的舒适性而且应该在设计师的设计中得到体现,可是设计师们在他们的设计工作中有多少成功的满足了这一要求呢?在过去的20年里消费者运动的大规模增长反映了消费者对产品以及服务的不满。更准确的说消费者的不满在安全方面,安全保障的缺失已经引起了法院和立法机关的重视,特别是在美国。

在1963年,加州最高法院裁定,“当制造商生产劣质产品并将其投放到市场上时买卖,之前又没有用探伤仪检测,结果证明这导致了人身伤害,那么他就已经严重侵犯了他人的权益”。加州政府的决策被许多州效仿结果导致了20世纪70年代美国的产品责任危机,尽管那时有立法,但是据估计在1973年仍然有超过600000人发生和产品质量相关的事故。由于这个问题波及的巨大范围带来的影响,同年美国消费者产品安全委员会成立,该委员会的只要责任是减少由消费品所引起的意外伤害,并设立了强制性的安全标准,如果有必要的话,还要禁止劣质产品买卖并召回有问题的产品。

在欧洲,法庭的判决会使很多受伤的消费者的身心压力得到缓解,可是他们不会介绍关于人身侵犯方面应该依据产品安全保障法方面的知识,因为这是加利福尼亚最高法院的职责。例如反应停灾害事件,它将问题集中在法律修改有问题的产品方面以帮助那些因为使用劣质产品而受伤的人,如果他们已经亲自购买了这些产品,依据现有具体的法律法规很容易使消费者得到补偿,但如果受害者不是直接的购买者,补救是很难的,而如果他是,则他的权益是可以得到保障的。

在欧洲也发生了和美国一样的事故。BEUC是一所专门为消费者服务的组织,它在1985年针对消费者的安全问题发表了一篇报告,报告里引用了EEC组织的调查结果,平均每年有30000人死亡,而在1984这一年就有4000000人因为类似的事故受伤。

在20世纪70年代英国和欧洲各机构审议认为严格的产品责任制是侵权行为。在1977年欧洲理事会举办了关于产品安全责任公约的签字仪式。公约规定生产者要赔偿因为它所生产的产品缺陷引起的伤亡事件。由于产品责任落实的草案还处于讨论阶段,因此大多数成员国表示不愿意接受这一条约,这一草案已经在1976年就被EEC 委员会谈论过,在1979年修正,而在1985年才最后被各成员国承认接受。但与这个条约不同,依照现有规章制度,这个立案需要在1988年7月30日前通过立法审核。

从设计师的角度来看,客观的讲该法令中关键条款是第1和第6条以及(b),(d),(e)和(f号中的第7条)。

第1条规定:生产者应当承担由于自己的产品缺陷所造成的损害。

第6条规定如下:

(1)产品不能提供安全保障时它就是有缺陷的,而使用者有权利将以下因素考虑在内:

(a)产品说明书;

(b) 商品可以根据正常思维习惯判断起适用方式;

(c)产品的保质期;

(2)对于现有产品不得因为其改良产品投入市场而被认为存在缺陷;

第7条中规定了对于制造商的限制,而下面这些则和设计问题有关,内容如下:(b)产品投入生产或者某种缺陷后来出现时,这种导致伤害的产品缺陷就应该被改良处理;

(d)因为产品不符合由公众当局提议的强制性的规章制度时,这种设计应该被禁止再次出现;

(e)当时的科学技术知识还不足以发现现存的产品缺陷;

(f)对一个配件的制造商而言,产品缺陷要归咎于产品的设计问题,而在整个产品的设计过程中配件的安装要依据产品生产商国提供的说明资料;

根据第8章的规定,在由于在产品缺陷和使用方疏忽的共同情况下,受害方是要负责的,而生产商的责任是“减少和杜绝”的这类情况的发生。该指令第19条规定成员国要在1988年7月底前将“符合本指令的法律,法规和行政规定”赋予法律效力。

针对安全性能的设计

在本单元中对安全的强调使得产品的安全成为了设计师在设计中需要考虑的

必要元素。毫无疑问,很多设计师一直都在把安全作为产品设计中的必要部分,可是很多与产品质量有关的事故和人身伤害的事实表明一些设计师还没有将安全性能摆在一个重要的位置。在一本由南美保险公司印制的宣传册上记载,设计缺陷和生产缺陷是经常引起责任纠纷的原因。可小册子中指出,有21%的事件是由于无效的警告提示造成的,因此设计师一定要在考虑使用舒适性时,注意所设计产品的质量问题和方便后续加工,产品本身是不能有效的对使用者的安全进行提示的,因此,警告会对人身造成伤害的操作的提示是非常有必要的。在检查产品时,法律有必要设定一个具体标。

在评估过程中,生产商需要考虑产品的说明书规范,在产品使用时,使用者可以根据预判对产品的使用有所了解,当不符合这种要求时,其缺陷就是确定的,这就意味着该“产品”的相关内容就必须修改,其中包括:

1.产品本身;

2.标签;

3.包装;

4.容器;

5.安装/使用说明;

6.保修文件;

7.售楼书;

8.备件;

9.广告材料;

10.目录。

如果生产商希望利用保护法中的第7条(b),将需要证据证明该产品在进入市场时其自身缺陷是不存在的。保护法(四)要求设计人员必须熟悉由有关当局签发的强制性的相关条例和相关公共标准。保护法(五)要求设计师将科学和技术方面的最新动态与相关产品相结合已达到改进的目的。保护法还要求产品设计师们可以作为产品的一部分做好本职工作,所设计的产品是可以使用或者已经是改进了由供应商提供的先前产品已有的缺陷。

美国的市场安全报告中指出,“任何产品的发展和设计活动都包括准备阶段和相持阶段。这也是最重要的,因为一旦产品性能规格已选定,并一直延续于设计研究中,那么它在很大程度上将决定产品的发展是什么样的过程,而且考虑产品原材

料和材料的质量品质控制都是必要的。设计的缺陷不同于生产缺陷,它会影响所有此类产品的生产和应用,因此设计上的瑕疵也应该对产品的可靠性负责。

Design Implications of Product

Liability

by

J.G. Roche

Fitness for use is judged not by the designer, manufacturer or retailer but by the

user. Juran et al. [1] identify the following as the major parameters of fitness for use: — Quality of Design,

— Quality of Conformance,

— The "abilities",

— Field service.

Quality of Design "can be regarded as a composite of three separate steps in

a common progression of activities:

(1) Identification of what constitutes fitness for use to the user;

(2) Choice of a concept of product or service to be responsive to the identified

needs of the user;

(3) Translation of the chosen product concept into a detailed set of specifications which, if faithfully executed, will then meet the users' needs."

Juran's[l] four parameters of fitness for use and their inter-relationships are shown

in Figure 1.

As is implied in Figure 1, Quality of Design is influenced by the quality of market research. Market inputs may be vague and the designer or design team may have

to frame a design concept with incomplete market information. But market input

is just one of the inputs which make up the designer's brief. Knowledge of the

production facilities available and their capabilities is essential as is knowledge

of the process involved in production. Does the workforce have the necessary skills? What materials are available and what do they cost; What will production costs be? Are they expected to be too high in the light of the expected selling price? For many engineering products, reliability and maintainability requirements need to be determined. The ready availability of spare parts may be crucial for some products. Likewise, field service may be of major importance.

The Arrival of Strict Product Liability

These then are the factors which influence "Fitness for Use" and which should

be expressed or implied in the designer's brief. But how successful have designers been in achieving fitness for use in the products which they have designed? The remarkable growth of the consumer movement in the past twenty years is a reflection of widepread dissatisfaction with products and services available. One aspect of consumer dissatisfaction, safety or more correctly, the lack of safety,

has received particular attention in courts and in legislatures, especially in the US. In 1963, the Supreme Court of California ruled that "A manufacturer is strictly liable in tort when an article he places on the market, knowing that it is to be

used without inspection for defects, proves to have a defect which causes injury

to a human being". This Californian decision was followed by many other states and led to the "Product Liability Crisis" of the early 1970s in the US. Despite

this legal background, it was estimated that in 1973 there were over six million

product-associated accidents in the US. The sheer size of the problem led to the establishment of the US Consumer Product Safety Commission (CPSC) in 1973. The Commission's main task is to reduce unreasonable risks of injury associated with consumer products. It can set mandatory safety standards, ban products and order recalls if necessary.

In Europe, court decisions eased the lot of injured consumers. But the courts

did not introduce strict product liability in tort as did the Californian Supreme Court. However, events such as the thalidomide disaster focused attention on the need

for legal changes to assist persons injured by defective products. If the injured person has purchased the product, existing contract laws make it comparatively easy to obtain redress. But if the injured person is not the purchaser, redress

is very difficult, if not impossible, to secure.

The accident toll in Europe was, as in the US, horrendously high. In 1985, BEUC, the European organisation for consumers, published a report on consumer safety. The report quoted EEC Commission estimates that there were 30,000 deaths

per year and 40 million injuries due to domestic accidents in 1984[2].

During the 1970s various British and European organisations considered the introduction of strict product liability in tort. The Council of Europe opened the Convention on Products Liability to signature by the Member States in 1977. The Convention made "the producer" liable to pay compensation for death or personal injuries caused by a defect in his product. But few Member States of the Council

of Europe were willing to adopt the Convention as there was also a Draft Directive on Product Liability under discussion. This Draft had been issued by the EEC Commission in 1976; it was amended in 1979 and was finally adopted in July 1985. Unlike the Convention, the Directive requires Member States to pass legislation conforming to the Directive on or before 30 July 1988.

From the viewpoint of the designer, the critical articles of the Directive are Articles 1 and 6 and (b), (d), (e) and (f) of Article 7. Article 1 states:

The producer shall be liable for damage caused by a defect in his product.

Article 6 defines a defective product as follows:

(1) A product is defective when it does not provide the safety which a person is entitled to

expect, taking all circumstances into account, including:

(a) the presentation of the product;

(b) the use to which it could reasonably be expected that the product would be put;

(c) the time when the product was put into circulation.

(2) A product shall not be considered defective for the sole reason that a better product is subsequently put into circulation.

Article 7 describes defences available to the producer; only those relevant to design

are reproduced here:

(b) that, having regard to the circumstances, it is probable that the defect which caused the

damage did not exist at the time when the product was put into circulation or that this defect came into being afterwards; or

(d) that the. defect is due to compliance of the product with mandatory regulations issued by

the public authorities; or

(e) that the state of scientific and technical knowledge at the time was not such as to enable

the existence of the defect to be discovered; or

(f) in the case of a manufacturer of a component, that the defect is attributable to the design

of the product in which the component has been fitted or to the instructions given by the manufacturer of the product.

According to Article eight, the producer's liability may be "reduced or disallowed"

in cases where there is both a product defect and contributory negligence by the

injured party or by a person for whom the injured party is responsible. Article

19 of the Directive requires Member States to bring into force "the laws, regulations and administrative provisions necessary to comply with this Directive" before

the end of July 1988.

Design for Safety

The emphasis on safety in this Directive makes product safety an essential component of the designer's brief. Undoubtedly, many designers have always regarded safety as an essential part of product design. But the evidence of so many product-related accidents and injuries indicates that some designers have

not given safety its due prominence. A booklet[3] produced by Insurance Company of North America states that design and manufacturing defects were the most frequently alleged cause of liability suits (39 per cent and 37 per cent). But the booklet also notes that "failure to warn" defects were cited in 21 per cent of the cases. So in considering Fitness for Use the designer must pay attention not merely to the design quality but also to Quality of Conformance. When hazards can not

be effectively designed out of products, appropriate warnings are an obvious requirement.

In assessing defectiveness our courts will have to determine the safety to which

a person is entitled to expect. In this assessment the court is required to take

into account the presentation of the product, the use to which it could reasonably be expected that the product could be put and the time when the product was

put into circulation. When defectiveness is determined in this fashion, it means that the definition of "product" must be revised to include:

— the actual product,

— labels,

— packaging,

— container,

— installation/use instructions,

— warranty documents,

— sales brochures,

— spare parts,

— advertising material,

— catalogues.

If the producer wishes to avail of defence (b) in Article 7, evidence will be required

to show that the defect did not exist at the time that the product was put into circulation. Defence (d) will require designers to be familiar with mandatory regulations or standards issued by the relevant public authorities. Defence (e)

will require the designer to keep abreast of scientific and technical developments that are relevant to the product in question. Defence (0 will require the designer

of a product used as a component to be sufficiently competent to be able to show that it was the design of the product in which the component was fitted or the instructions given by the manufacturer of the product that caused the damage.

The American report Safety in the Market Place notes that "for any product,

the development and design activities comprise the most fluid stage in its preparation for the market place. It is also one of the most important, for once performance specifications have been selected and the design has been committed, it will dictate in large measure what processes, materials and quality control procedures will be required" [4]. A design defect, unlike a production defect, affects all items p policies. roduced. A design defect may also nullify the shield of product liability insurance .

外文出处: 《Exploiting Software How to Break Code》By Greg Hoglund, Gary McGraw Publisher : Addison Wesley Pub Date : February 17, 2004 ISBN : 0-201-78695-8 译文标题: JDBC接口技术 译文: JDBC是一种可用于执行SQL语句的JavaAPI(ApplicationProgrammingInterface应用程序设计接口)。它由一些Java语言编写的类和界面组成。JDBC为数据库应用开发人员、数据库前台工具开发人员提供了一种标准的应用程序设计接口,使开发人员可以用纯Java语言编写完整的数据库应用程序。 一、ODBC到JDBC的发展历程 说到JDBC,很容易让人联想到另一个十分熟悉的字眼“ODBC”。它们之间有没有联系呢?如果有,那么它们之间又是怎样的关系呢? ODBC是OpenDatabaseConnectivity的英文简写。它是一种用来在相关或不相关的数据库管理系统(DBMS)中存取数据的,用C语言实现的,标准应用程序数据接口。通过ODBCAPI,应用程序可以存取保存在多种不同数据库管理系统(DBMS)中的数据,而不论每个DBMS使用了何种数据存储格式和编程接口。 1.ODBC的结构模型 ODBC的结构包括四个主要部分:应用程序接口、驱动器管理器、数据库驱动器和数据源。应用程序接口:屏蔽不同的ODBC数据库驱动器之间函数调用的差别,为用户提供统一的SQL编程接口。 驱动器管理器:为应用程序装载数据库驱动器。 数据库驱动器:实现ODBC的函数调用,提供对特定数据源的SQL请求。如果需要,数据库驱动器将修改应用程序的请求,使得请求符合相关的DBMS所支持的文法。 数据源:由用户想要存取的数据以及与它相关的操作系统、DBMS和用于访问DBMS的网络平台组成。 虽然ODBC驱动器管理器的主要目的是加载数据库驱动器,以便ODBC函数调用,但是数据库驱动器本身也执行ODBC函数调用,并与数据库相互配合。因此当应用系统发出调用与数据源进行连接时,数据库驱动器能管理通信协议。当建立起与数据源的连接时,数据库驱动器便能处理应用系统向DBMS发出的请求,对分析或发自数据源的设计进行必要的翻译,并将结果返回给应用系统。 2.JDBC的诞生 自从Java语言于1995年5月正式公布以来,Java风靡全球。出现大量的用java语言编写的程序,其中也包括数据库应用程序。由于没有一个Java语言的API,编程人员不得不在Java程序中加入C语言的ODBC函数调用。这就使很多Java的优秀特性无法充分发挥,比如平台无关性、面向对象特性等。随着越来越多的编程人员对Java语言的日益喜爱,越来越多的公司在Java程序开发上投入的精力日益增加,对java语言接口的访问数据库的API 的要求越来越强烈。也由于ODBC的有其不足之处,比如它并不容易使用,没有面向对象的特性等等,SUN公司决定开发一Java语言为接口的数据库应用程序开发接口。在JDK1.x 版本中,JDBC只是一个可选部件,到了JDK1.1公布时,SQL类包(也就是JDBCAPI)

Structured programming is still the most dominant approach to software engineering and is still evo lving. These failures led to the concept of "software engineering" based upon the idea that an engineering-like discipl ine could be applied to software design and develop ment. Software design is a process where the software designer applies techniques and principles to produce a conceptual model that de scribes and defines a solution to a problem.

Interaction design Moggridge Bill Interaction design,Page 1-15 USA Art Press, 2008 Interaction design (IxD) is the study of devices with which a user can interact, in particular computer users. The practice typically centers on "embedding information technology into the ambient social complexities of the physical world."[1] It can also apply to other types of non-electronic products and services, and even organizations. Interaction design defines the behavior (the "interaction") of an artifact or system in response to its users. Malcolm McCullough has written, "As a consequence of pervasive computing, interaction design is poised to become one of the main liberal arts of the twenty-first century." Certain basic principles of cognitive psychology provide grounding for interaction design. These include mental models, mapping, interface metaphors, and affordances. Many of these are laid out in Donald Norman's influential book The Psychology of Everyday Things. As technologies are often overly complex for their intended target audience, interaction design aims to minimize the learning curve and to increase accuracy and efficiency of a task without diminishing usefulness. The objective is to reduce frustration and increase user productivity and satisfaction. Interaction design attempts to improve the usability and experience of the product, by first researching and understanding certain users' needs and then designing to meet and exceed them. (Figuring out who needs to use it, and how those people would like to use it.) Only by involving users who will use a product or system on a regular basis will designers be able to properly tailor and maximize usability. Involving real users, designers gain the ability to better understand user goals and experiences. (see also: User-centered design) There are also positive side effects which include enhanced system capability awareness and user ownership. It is important that the user be aware of system capabilities from an early stage so that expectations regarding functionality are both realistic and properly understood. Also, users who have been active participants in a product's development are more likely to feel a sense of ownership, thus increasing overall satisfa. Instructional design is a goal-oriented, user-centric approach to creating training and education software or written materials. Interaction design and instructional design both rely on cognitive psychology theories to focus on how users will interact with software. They both take an in-depth approach to analyzing the user's needs and goals. A needs analysis is often performed in both disciplines. Both, approach the design from the user's perspective. Both, involve gathering feedback from users, and making revisions until the product or service has been found to be effective. (Summative / formative evaluations) In many ways, instructional

Injection Molding The basic concept of injection molding revolves around the ability of a thermoplastic material to be softened by heat and to harden when cooled .In most operations ,granular material (the plastic resin) is fed into one end of the cylinder (usually through a feeding device known as a hopper ),heated, and softened(plasticized or plasticized),forced out the other end of the cylinder, while it is still in the form of a melt, through a nozzle into a relatively cool mold held closed under pressure.Here,the melt cools and hardens until fully set-up. The mold is then opened, the piece ejected, and the sequence repeated. Thus, the significant elements of an injection molding machine become: 1) the way in which the melt is plasticized (softened) and forced into the mold (called the injection unit); 2) the system for opening the mold and closing it under pressure (called the clamping unit);3) the type of mold used;4) the machine controls. The part of an injection-molding machine, which converts a plastic material from a sold phase to homogeneous seni-liguid phase by raising its temperature .This unit maintains the material at a present temperature and force it through the injection unit nozzle into a mold .The plunger is a combination of the injection and plasticizing device in which a heating chamber is mounted between the plunger and mold. This chamber heats the plastic material by conduction .The plunger, on each stroke; pushes unbelted plastic material into the chamber, which in turn forces plastic melt at the front of the chamber out through the nozzle The part of an injection molding machine in which the mold is mounted, and which provides the motion and force to open and close the mold and to hold the mold close with force during injection .This unit can also provide other features necessary for the effective functioning of the molding operation .Moving

DESIGN and ENVIRONMENT Product design is the principal part and kernel of industrial design. Product design gives uses pleasure. A good design can bring hope and create new lifestyle to human. In spscificity,products are only outcomes of factory such as mechanical and electrical products,costume and so on.In generality,anything,whatever it is tangibile or intangible,that can be provided for a market,can be weighed with value by customers, and can satisfy a need or desire,can be entiled as products. Innovative design has come into human life. It makes product looking brand-new and brings new aesthetic feeling and attraction that are different from traditional products. Enterprose tend to renovate idea of product design because of change of consumer's lifestyle , emphasis on individuation and self-expression,market competition and requirement of individuation of product. Product design includes factors of society ,economy, techology and leterae humaniores. Tasks of product design includes styling, color, face processing and selection of material and optimization of human-machine interface. Design is a kind of thinking of lifestyle.Product and design conception can guide human lifestyle . In reverse , lifestyle also manipulates orientation and development of product from thinking layer.

The mold designing and manufacturing The mold is the manufacturing industry important craft foundation, in our country, the mold manufacture belongs to the special purpose equipment manufacturing industry. China although very already starts to make the mold and the use mold, but long-term has not formed the industry. Straight stabs 0 centuries 80's later periods, the Chinese mold industry only then drives into the development speedway. Recent years, not only the state-owned mold enterprise had the very big development, the three investments enterprise, the villages and towns (individual) the mold enterprise's development also rapid quietly. Although the Chinese mold industrial development rapid, but compares with the demand, obviously falls short of demand, its main gap concentrates precisely to, large-scale, is complex, the long life mold domain. As a result of in aspect and so on mold precision, life, manufacture cycle and productivity, China and the international average horizontal and the developed country still had a bigger disparity, therefore, needed massively to import the mold every year . The Chinese mold industry must continue to sharpen the productivity, from now on will have emphatically to the profession internal structure adjustment and the state-of-art enhancement. The structure adjustment aspect, mainly is the enterprise structure to the specialized adjustment, the product structure to center the upscale mold development, to the import and export structure improvement, center the upscale automobile cover mold forming analysis and the structure improvement, the multi-purpose compound mold and the compound processing and the laser technology in the mold design manufacture application, the high-speed cutting, the super finishing and polished the technology, the information direction develops . The recent years, the mold profession structure adjustment and the organizational reform step enlarges, mainly displayed in, large-scale, precise, was complex, the long life, center the upscale mold and the mold standard letter development speed is higher than the common mold product; The plastic mold and the compression casting mold proportion increases; Specialized mold factory quantity and its productivity increase;

附件1:外文资料翻译译文 基于一维CFD模型下汽车排气消声器的实验研究与预测Takeshi Yasuda, Chaoqun Wua, Noritoshi Nakagawa, Kazuteru Nagamura 摘要目前,利用实验和数值分析法对商用汽车消声器在宽开口喉部加速状态下的排气噪声进行了研究。在加热工况下发动机转速从1000转/分钟加速到6000转/分钟需要30秒。假定其排气消声器的瞬时声学特性符合一维计算流体力学模型。为了验证模拟仿真的结果,我们在符合日本工业标准(JIS D 1616)的消声室内测量了排气消声器的瞬态声学特性,结果发现在二阶发动机转速频率下仿真结果和实验结果非常吻合。但在发动机高阶转速下(从5000到6000转每分钟的四阶转速,从4200到6000转每分钟的六阶转速这样的高转速范围内),计算结果和实验结果出现了较大差异。根据结果分析,差异的产生是由于在模拟仿真中忽略了流动噪声的影响。为了满足市场需求,研究者在一维计算流体力学模型的基础上提出了一个具有可靠准确度的简化模型,相对标准化模型而言该模型能节省超过90%的执行时间。 关键字消声器排气噪声优化设计瞬态声学性能 1 引言 汽车排气消声器广泛用于减小汽车发动机及汽车其他主要部位产生的噪声。一般而言,消声器的设计应该满足以下两个条件:(1)能够衰减高频噪声,这是消声器的最基本要求。排气消声器应该有特定的消声频率范围,尤其是低频率范围,因为我们都知道大部分的噪声被限制在发动机的转动频率和它的前几阶范围内。(2)最小背压,背压代表施加在发动机排气消声器上额外的静压力。最小背压应该保持在最低限度内,因为大的背压会降低容积效率和提高耗油量。对消声器而言,这两个重要的设计要求往往是互相冲突的。对于给定的消声器,利用实验的方法,根据距离尾管500毫米且与尾管轴向成45°处声压等级相近的排气噪声来评估其噪声衰减性能,利用压力传感器可以很容易地检测背压。 近几十年来,在预测排气噪声方面广泛应用的方法有:传递矩阵法、有限元法、边界元法和计算流体力学法。其中最常用的方法是传递矩阵法(也叫四端网络法)。该方

Section 3 Design philosophy, design method and earth pressures 3.1 Design philosophy 3.1.1 General The design of earth retaining structures requires consideration of the interaction between the ground and the structure. It requires the performance of two sets of calculations: 1)a set of equilibrium calculations to determine the overall proportions and the geometry of the structure necessary to achieve equilibrium under the relevant earth pressures and forces; 2)structural design calculations to determine the size and properties of thestructural sections necessary to resist the bending moments and shear forces determined from the equilibrium calculations. Both sets of calculations are carried out for specific design situations (see 3.2.2) in accordance with the principles of limit state design. The selected design situations should be sufficiently Severe and varied so as to encompass all reasonable conditions which can be foreseen during the period of construction and the life of the retaining wall. 3.1.2 Limit state design This code of practice adopts the philosophy of limit state design. This philosophy does not impose upon the designer any special requirements as to the manner in which the safety and stability of the retaining wall may be achieved, whether by overall factors of safety, or partial factors of safety, or by other measures. Limit states (see 1.3.13) are classified into: a) ultimate limit states (see 3.1.3); b) serviceability limit states (see 3.1.4). Typical ultimate limit states are depicted in figure 3. Rupture states which are reached before collapse occurs are, for simplicity, also classified and
