Chapter 7 Ergonomics

Unit 1 Introduction to Ergonomics

Definition of Ergonomics

What is ergonomics (sometimes called human factors)? Most people think it is something to do with seating or with the design of car controls and instruments. It is…but it is much more! Ergonomics is the scientific discipline concerned with the understanding of interaction among humans and other element of a system, and the profession that applies theory, principles, data and methods to design in order to optimize human being activities and overall system performance. In other words, ergonomics is the application of scientific information concerning humans to the design of objects, systems and environment for human use. Ergonomics is an effective approach which puts human needs and capabilities at the focus of designing technological system. Until now, Ergonomics comes into everything which involves people, such as work systems, sports and leisure, health , safety , and so on.

人体工程学的定义

什么是人体工程学(有时称为人为因素)?大多数人认为这是什么与阀座或设计的汽车控制和仪器。这是…但

它是更多!人体工程学是科学学科关心理解人类和其他元素之间的交互的系统,和行业应用的理论、原则、

数据和方法来设计以优化人类活动和整个系统的性能。换句话说,人类工程学是应用程序的科学信息涉及人

类设计的对象、系统和环境给人类使用。人体工程学是一种有效的方法将人类的需求和能力的重点技术系

统设计。直到现在,人类工程学进入所有涉及的人,比如工作系统、运动、休闲、健康、安全,等等。

Aim of Ergonomics

Why do some car seats leave you aching after a long journey? why do some computer workstations result in eyestrain and muscle fatigue ? such human inconveniences are not inevitable? what is the aim of ergonomics ? the aim of ergonomics is to ensure that humans and technology work in complete harmony , with the equipment and tasks aligned to human characteristics.人体工程学的目的

为什么有些汽车座椅让你疼痛的经过一段漫长的旅程吗?为什么有些电脑工作站导致眼睛疲劳和肌肉疲劳吗?这样的人类不便并不是不可避免的吗?人体工程学的目的是什么?人体工程学的目的是确保人类和技术

工作水乳交融,设备和任务对齐到人类的特性。

The ergonomist work in teams which may involve a variety of other professions: design engineers, production engineers, industrial designers, computer specialists, industrial physicians , health and safety practitioners ,and specialists in human resources . the overall aim is to ensure the knowledge of human characteristics is brought to bear on practical problem of people at work and in leisure . in many case ,unsuitable conditions lead often to inefficiency ,error , unacceptable stress ,and physical or mental cost.

在团队中工作的工作可能涉及到各种各样的其他职业:设计工程师、生产工程师、工业设计师、电脑专家、工业医师、健康和安全从业人员,人力资源和专家。整体目标是要确保人类特征的知识是施加了实际问

题的人在工作中以及在休闲。在许多情况下,不合适的条件下领导经常效率低下,错误,不可接受的压力、身

体或精神上的成本。

Ergonomists study human capabilities in relationship to work demands , contribute to the design and evaluation of tasks , jobs , products , environments and systems in order to make them compatible with the needs , abilities and limitations of people . Practicing ergonomists must have a board understanding of the full scope of the discipline . Ergonomics promotes a complete approach which takes considerations of physical , cognitive , environmental , organizational , social and other relevant factors into account .

人类工程学家研究人类的能力在工作要求的关系,为设计和评估的任务、工作、产品、环境和系统以使其兼

容的需要、能力和局限性的人。练习生物工程学者们必须有董事会的理解纪律的充分的范围。人体工程学

促进一个完整的方案需要考虑身体、认知、环境、组织、社会及其它相关因素考虑在内。

Origins of Ergonomics

The term “ergonomics” is derived from the Greek words ergon ( means work ) and nomoi (means natural laws ) to express the systems-oriented discipline which now extends across all aspects of human activity .人体工程学的起源

“人体工程学”这个词来源于希腊语单词ergon(意味着工作)和nomoi(意味着自然法则)来表达成现在的纪律,跨越了所有方面的人类活动。

Ergonomics is a relatively new branch of science Which originated in the middle of 20th century , but relies on research carried out in many other older, established scientific areas , such as engineering, physiology and psychology in world war 2 ,when scientists designed advanced new and potentially improved systems without fully considering the people who would be using them , it gradually became clear that systems and account if they are to be used safely and effectively . this awareness of people’s requirements resulted in the discipline of ergonomics . the multi-disciplinary nature of ergonomics is immediately obvious.

人体工程学是一种相对较新的科学的分支,起源于20世纪中期,而是依靠开展的研究在许多其他年长的、确定的科学领域,如工程、生理学和心理学在二次世界大战,当科学家们设计先进的新的潜在改进系统

没有充分全面考虑将使用它们的人,它渐渐清晰,系统和帐户,如果要使用安全并且有效的。这对于人们的需

求导致人体工程学的纪律。人体工程学的多学科的本质是显而易见的。

Ergonomics deals with the interaction of technological and work situations with the human being .The basic human sciences involved are anthropometry ,physiology and psychology .These sciences are applied by the ergonomist towards two main objectives :the most productive use of human capabilities ,and the maintenance of human health .In a phrase ,the job must “fit the person ” in all aspects ,and the work situation should be beyond human capabilities and limitations人体工程学处理

个主要目标改善:最高效地利用人类的能力,和维护人类健康。在一个短语,这项工作必须“合适的人”在所有方面,和工作情况应该超越人类能力和局限性.

Anthropometry contributes to improve “ physical fit ” between people and the things they use ranging from hand tools to aircraft cockpit design .Achieving good “physical fit ” is no mean feat when one considers the range in human body sizes

across the postures .

。

人体尺寸有助于改善“身体健康”与人类之间的事情,他们使用从手工具对飞机座舱设计。达到好的“身体健康”是得不偿失的,当一个人考虑人体大小不等的整个姿势。

Anthropometry provides data on dimensions of the human body ,in various postures .人体测量提供了数据在人体的尺寸,在各种姿势。

Physiology supports two main technical areas . Work physiology deals with the energy requirements of the body and sets standards for acceptable physical work-rate and workload, and for nutrition requirements ,Environmental physiology analyses the impact of physical working conditions-thermal , noise and vibration ,and lighting –and sets the optimum requirements for these.

生理支持两种主要技术领域。工作与能源需求的生理交易的身体并制定了可接受的物理的跑动和工作负载,为营养需求,环境生理分析了影响的物理工作情况-热气流、噪音和振动,和照明——集最优要求这些。

Psychology is concerned with human information processing and decision-making capabilities. In simple terms, this can be seen as aiding the ‘cognitive fit’ between people and the things they use. Relevant topics are sensory processes, understanding, long-and short-term memory, decision-making and action. The importance of psychological dimensions ergonomist ergonomics should not be underestimated in today’s ‘high-tech’ word. The ergonomist advises on the design of interfaces between people and computers, information displays for industrial processes, the planning of training materials, and the design of human tasks and jobs. The concept of information overload is familiar in many current jobs. Increasing automation will frequently increase the mental demands in terms of monitoring, supervision and maintenance

。

心理学是有关人类信息处理和决策能力。简单来说,这可以被视为帮助“认知健康的人与他们使用的东西。相关主题是感官的过程,理解,长短期记忆、决策和行动。心理维度的重要性不应低估改善人体工程学在今天的“高科技”字。改善的建议人们之间的接口的设计和计算机,对工业过程的信息显示,计划的培训材料,设计的人工任务和工作。信息超载的概念在许多现在的工作很熟悉。增加自动化经常会增加精神需求方面的监测、监督和维护。

第一章汽车总论 1)Today’s average car contains more than 15,000 separate, individual parts that must work together. These parts can be grouped into four major categories: body, engine, chassis and electrical equipment 。P1 现在的车辆一般都由15000多个分散、独立且相互配合的零部件组成。这些零部件主要分为四类：车身、发动机、底盘和电气设备。 2)The engine acts as the power unit. The internal combustion engine is most common: this obtains its power by burning a liquid fuel inside the engine cylinder. There are two types of engine: gasoline (also called a spark-ignition engine) and diesel (also called a compression-ignition engine). Both engines are called heat engines; the burning fuel generates heat which causes the gas inside the cylinder to increase its pressure and supply power to rotate a shaft connected to the power train. P3 发动机作为动力设备，常见的类型是内燃机，其原理是通过发动机缸内的液体燃料燃烧而产生能量。发动机可分为两类：汽油机（点燃式）和柴油机（压燃式），都属于热力发动机。燃料燃烧产生热量使缸内气压上升，产生的能量驱动轴旋转，并传递给动力传动系。 第二章内燃机 1)Power train system: conveys the drive to the wheels 2)Steering system: controls the direction of movement 3)Suspension system: absorbs the road shocks 4)Braking system: slows down the vehicle P4 传动系把发动机输出的扭矩传递给驱动轮。传动系包括离合器（对应机械变速器）或液力变矩器（对应液力自动变速器）、变速器、驱动轴、主减速器、差速器和驱动桥。 5)Drum brakes have a drum attached to the wheel hub, and braking occurs by means of brake shoes expanding against the inside of the drum. With disc brakes, a disc attached to the wheel hub is clenched between two brake pads. P6 鼓式制动器的制动鼓和轮毂连接，制动蹄张开压紧制动鼓内侧从而产生制动。在盘式制动器上，连着轮毂的制动盘被紧紧夹在两个制动块之间。 1)Linking the piston by a connecting rod to a crankshaft causes the gas to rotate the shaft through half a turn.The power stroke"uses up"the gas,so means must be provided to expel the burnt gas and recharge the cylinder with a fresh petrol-air mixture:this control of gas movement is the duty of the valves;An inlet valve allows the mixture to enter at the right time and an exhaust valve lets out the burnt gas after the gas has done its job . P10 活塞通过连杆和曲轴连接，使得气体带动曲轴旋转半圈。作功冲程耗尽了所有的气体，这样就必须采取相应的措施排出废气并且向气缸内充入新的可燃混合气：气体的运动由气门来控制。进气门使可燃混合气在恰当的时刻进入气缸，排气门使燃烧后的废气排出气缸。 2)The spark-ignition engine is an internal-combustion engine with externally supplied in ignition,which converts the energy cntained in the fuel to kinetic energy.The cycle of operations is spread over four piston strokes. To complete the full cycle it takes two revolutions of the crankshaft. P11 火花点火式发动机是由外部提供点火的内燃机，从而将含在燃料内的能量转化成动能。发动机的一个工作循环分布在活塞的四个行程中，一个完整的工作循环曲轴需要转动两圈。 3)The oil pump in the lubricating system draws oil from the oil pan and sends it to all working parts in the engine. The oil drains off and runs down into the pan. Thus,there is constant circulation of oil between the pan and the working parts of the engine. P15

About car engine Of all automobile components,an automobile engie is the most complicated assembly with dominant effects on the function of an autombile.So, the engine is generally called the"heat"of an automobile. 在汽车的所有部件中，汽车发动机是最复杂的组件，其对整车性能有着决定性的作用。因而发动机往往被称作发动机的“心脏”。 There are actually various types of engines such as electric motors,stream engines,andinternal combustion engines.The internal combustion engines seem to have almost complete dominance of the automotive field.The internal combustion engine,as its name indicates,burns fuel within the cylinders and converts the expanding force of the combustion into rotary force used to propel the vehicle. 事实上，按动力来源分发动机有很多种，如电动机、蒸汽机、外燃机等。然而内燃机似乎在发动机领域有着绝对的统治地位。就像其字面意思一样，内燃机的染料在气缸内燃烧，通过将燃烧产生气体的膨胀力转换成转动力来驱动发动机前进。 Engine is the power source of the automobile.Power is produced by the linear motion of a piston in a cylinder.However,this linear motion must be changed into rotary motion to turn the wheels of cars or trucks.The puston attached to the top of a connecting rod by a pin,called a piston pin or wrist pin.The bottom of the connecting rod is attached to the crankshaft.The connecting rod transmits the up-and-down motion of the piston to the crankshaft,which changes it into rotary motion.The connecting rod is mounted on the crankshaft with large bearings called rod bearing.Similar bearings, called main bearings,are used to mount the crankshaft in the block. 发动机是整部车的动力来源。能量来自于活塞在气缸内的（往复）直线运动。然而这种（往复）直线运动必须要转换成旋转运动才能驱动车轮。活塞与连杆通过一个销来连接，这个销称为活塞销。连杆的下部连接于曲拐。连杆把活塞的上下往复运动传递给曲拐，从而将往复直线运动转变成旋转运动。连杆和曲拐的连接使用大的轴承，称之为连杆轴承，类似的轴承也用于将曲轴连接到机体，称之为主轴承。 They are generally two different types of cooling system:water-cooling system and air-cooling system.Water-cooling system is more common.The cooling medium, or coolant, in them is either water or some low-freezing liquid, called antifreeze.A water-cooling system consists of the engine water jacket, thermostat, water pump, radiator, radiator cap, fan, fan drive belt and neccessary hoses. 主要有两种类型的冷却系统：水冷和风冷。水冷系统更为普遍。系统所用冷却介质或是冷却液常委水或其他低凝固点液体，称为抗凝剂。一个完整的水冷系统包括机体水套，节温器，水泵，散热器，散热器罩，风扇，风扇驱动皮带和必需的水管。 A water-cooling system means that water is used as a cooling agent to circulate through the engine to absorb the heat and carry it to the radiator for disposal.The ebgine is cooled mainly through heat transfer and heat dissipation.The heat generated by the mixture burned in the engine must be transferred from the iron or aluminum cylinder to the waterin the water jacket.The outside of the water jacket dissipates some of the heat to the air surrounding it, but most of the heat is carried by the cooling water to the radiator for dissipation.When the coolant temperature in the system reaches 90°,the termostat valve open fully, its slanted edge shutting off

Unit 1 Safety Management Systems 安全管理体系 1.Accident Causation Models 1.事故致因理论 The most important aim of safety management is to maintain and promote workers' health and safety at work. Understanding why and how accidents and other unwanted events develop is important when preventive activities are planned. Accident theories aim to clarify the accident phenomena，and to explain the mechanisms that lead to accidents. All modem theories are based on accident causation models which try to explain the sequence of events that finally produce the loss. In ancient times, accidents were seen as an act of God and very little could be done to prevent them. In the beginning of the 20th century，it was believed that the poor physical conditions are the root causes of accidents. Safety practitioners concentrated on improving machine guarding, housekeeping and inspections. In most cases an accident is the result of two things ：The human act, and the condition of the physical or social environment. 安全管理系统最重要的目的是维护和促进工人们在工作时的健康和安全。在制定预防性计划时，了解为什么、怎样做和其他意外事故的发展是十分重要的。事故致因理论旨在阐明事故现象，和解释事故的机理。所有现代理论都是基于试图解释事件发生、发展过程和最终引起损失的事故致因理论。在古老的时期，事故被看做是上帝的行为并且几乎没有预防的方法去阻止他们。在20世纪开始的时候，人们开始相信差的物理条件是事故发生的根源。安全从业人员集中注意力在提高机器监护、维护和清理上。在大多数情况下，一件事故的发生主要有两个原因：人类的行为和物理或者社会环境。 Petersen extended the causation theory from the individual acts and local conditions to the management system. He concluded that unsafe acts, unsafe conditions，and accidents are all symptoms of something wrong in the organizational management system. Furthermore, he stated that it is the top management who is responsible for building up such a system that can effectively control the hazards associated to the organization’s operation. The errors done by a single person can be intentional or unintentional. Rasmussen and Jensen have presented a three-level skill-rule-knowledge model for describing the origins of the different types of human errors. Nowadays，this model is one of the standard methods in the examination of human errors at work. 彼得森根据管理体系中个人的行为结合当地的环境扩充了事故致因理论。他的结论是像不安全行为、不安全情况是一些错误的组织管理系统导致事故的征兆。另外，他指出，高层管理人员负责建立一个能够有效控制危险源有关组织。一个人出现的错误可能是有意的或者是无意的。拉斯姆森和杰森已经提出了三个层次的技能规则知识模型来描述不同种类的人错误的起源。如今，这种模式已经成为在工作中检验人的错误的标准之一。 Accident-proneness models suggest that some people are more likely to suffer anaccident than others. The first model was created in 1919，based on statistical examinations in a mumilions factory. This model dominated the safety thinking and research for almost 50 years, and it is still used in some organizations. As a result of this thinking, accident was blamed solely

Civil Engineering Civil engineering, the oldest of the engineering specialties, is the planning, design, construction, and management of the built environment. This environment includes all structures built according to scientific principles, from irrigation and drainage systems to rocket-launching facilities. 土木工程学作为最老的工程技术学科，是指规划，设计，施工及对建筑环境的管理。此处的环境包括建筑符合科学规范的所有结构，从灌溉和排水系统到火箭发射设施。 Civil engineers build roads, bridges, tunnels, dams, harbors, power plants, water and sewage systems, hospitals, schools, mass transit, and other public facilities essential to modern society and large population concentrations. They also build privately owned facilities such as airports, railroads, pipelines, skyscrapers, and other large structures designed for industrial, commercial, or residential use. In addition, civil engineers plan, design, and build complete cities and towns, and more recently have been planning and designing space platforms to house self-contained communities. 土木工程师建造道路，桥梁，管道，大坝，海港，发电厂，给排水系统，医院，学校，公共交通和其他现代社会和大量人口集中地区的基础公共设施。他们也建造私有设施，比如飞机场，铁路，管线，摩天大楼，以及其他设计用作工业，商业和住宅途径的大型结构。此外，土木工程师还规划设计及建造完整的城市和乡镇，并且最近一直在规划设计容纳设施齐全的社区的空间平台。 The word civil derives from the Latin for citizen. In 1782, Englishman John Smeaton used the term to differentiate his nonmilitary engineering work from that of the military engineers who predominated at the time. Since then, the term civil engineering has often been used to refer to engineers who build public facilities, although the field is much broader 土木一词来源于拉丁文词“公民”。在1782年，英国人John Smeaton为了把他的非军事工程工作区别于当时占优势地位的军事工程师的工作而采用的名词。自从那时起，土木工程学被用于提及从事公共设施建设的工程师，尽管其包含的领域更为广阔。 Scope. Because it is so broad, civil engineering is subdivided into a number of technical specialties. Depending on the type of project, the skills of many kinds of civil engineer specialists may be needed. When a project begins, the site is surveyed and mapped by civil engineers who locate utility placement—water, sewer, and power lines. Geotechnical specialists perform soil experiments to determine if the earth can bear the weight of the project.
