It is decision making process(often iterative),in which the basic sciences, mathematics, and engineering sciences are applied to convert resourcesoptimally to meet a sated objectives and criteria, synthesis, analysis,construction ,testing, and evaluation. The engineering design component of a curriculum must include most of the following features : development of student creativity, use of open-ended problem statement and use of modern design theory and methodology, formulation of design problem statement and specification, consideration of alternative solutions, feasibility considerations, production process, concurrent engineering design, and detailed system descriptions. Further, it is essential to include a variety of realistic constraints such as economic factors, safety, reliability, aesthetics, ethics, andsocial impact.31、what’s the main meaning of message (1)?A) Engineering design is a systematic process B) materials engineer’s mainworkC) mechanical engineer’s has good idea D) electrical engineer’ mainduty32、In the author’s opinion, the design process is very complex and should takeninto account many factors, from the message who should NOT join into the design team _______.A) environmentalists,B) sociologistsC) engineersD) Government officials33、From the message, we can know the meaning of words “ABET”(at line third paragraph) is _____.A) a set of accredits standardB) a kind of design methodC) a department of US government which responsible for engineering designD) A set of law34、It can be concluded from the passage that in the exercise and training of student, which character of the following is NOT included in the curriculum ______.A) creativityB) new materialC) ethicsD) economic factors35、The title of the message is ______.A) the roles of engineers in manufacturingB) the importance of mechanical designC) engineering designD) The process of machine designTEXT 2Working drawings are the complete set of standardized drawings specifying the manufacture and assembly of a product based on its design. The complexity of the design determines the number and types of drawings. Working drawings may be on more than one sheet and may contain written instructions called specifications.Working drawings are blueprints used for manufacturing products. Therefore, the set of drawings must:(a) completely describe the parts, both visually and dimensionally;(b)show the parts in assembly;(3)identify all the parts; and (4)specify standard parts. The graphics and text information must be sufficiently complete and accurate to manufacture and assemble the product without error.共 5 页第 2 页(1) Detail drawings of each nonstandard parts.(2) An assembly or subassembly drawing showing all the standard and nonstandard parts in a single drawing.(3) A bill of materials (BOM).(4) A title block.A detail drawing is a dimensioned, multiview drawing of a single part, describing the part’s shape, size, material, and surface roughness, in sufficient detail for the part to be manufactured based on the drawing alone. Detail drawings are produced from design sketches or extracted from 3-D computer models. They adhere strictly to ANSI standards and the standard for the specific company, for dimensioning, assigning part numbers, notes, tolerances, etc.In an assembly, standard parts such as threaded fasteners and bearings are not drawn as details, but are shown in the assembly view. Standard parts are not drawn as details because they are normally purchased, not manufactured, for assembly.For large assemblies or assembled with large parts, details are drawn on multiple sheets, and a separate sheet is used for the assembly view. If the assembly is simple or the parts are small,detail drawings for each part of an assembly can be placed on a singlesheet.TEXT 3One principle aim of kinematics is to create (design) the desired motions of the subjects’ mechanical parts and then mathematically compute the positions, velocities, and accelerations, which those will create on the parts. Since, for most earthbound mechanical systems, the mass remains essentially constant with time, defining the accelerations as a function of time then also defines the dynamic forces as a function of time. Stresses, in turn, will be a function of both applied and inertial (ma) forces. Since engineering design is charged with creating systems which will not fail during their expected service life, the goal is to keep stresses within acceptable limits for the materials chosen and the environmental conditions encountered. This obviously requires that all system forces be defined and kept within desired limits. In machinery, the largest forces encountered are often those due to the dynamics of the machine itself. These dynamic forces are proportional to acceleration, which brings us back to kinematics, the foundation of mechanical design. Very basic and early decision in the design process involving kinematic principles can be crucial to the success of any mechanical design; a design which has poor kinematics will prove troublesome and perform badly.Any mechanical system can be classified according to the number of degree of freedom (DOF) which it processes. The system’s DOF is equal to the number of independent parameters which are needed to uniquely define its position in space at any instant of time.A rigid body free to move within a reference frame will, in the general case, has complex motion, which is a simultaneous combination of rotation and translation. In three-dimensional space, there may be rotation about any axis and also simultaneous translation which can be resolved into components along three axes. In a plane, or two-dimensional space, complex motion becomes a combination of simultaneous rotation about one axis (perpendicular to the plane) and also translation resolved into components along two axes in the plane41、Kinematics research focus on the following EXCEPT ______..A) accelerations B) forceC) positions, D) velocities42、From the passage that for the design engineer the first and most important is____A) the service life of a machine B) the materials chooseC) the degree of freedom D) kinematic principles43、An mechanical system has uniquely defined position in space at any instant of time that ___.A) It should has one DOFB) It should Has two DOFC) the DOF and the number of independent parameters should equalD) It should has any DOF as want44、 which one of the following is NOT TRUE _______?.A) A rigid body free to move in three-dimensional space may rotation about anyaxisB) A rigid body free to move in three-dimensional space is a simultaneouscombination of rotation and translationC) A rigid body free to move in three-dimensional space can be resolved intocomponents along three axesD) A rigid body free to move in three-dimensional space may has complex motion45、The best title for this passage would be _______.A) kinematics B) dynamicsC) kinematics and dynamic D) the important of kinematics共 5 页第3 页1．将下列英语句子译成汉语（共5小题，每小题2分）（1）A perfectly rigid or inextensible link can exist only as a textbook type of model of a real machine member.（2）Foundations should ensure the machine’s stiffness; shock absorption and isolation are secondary considerations.(3)Thus, if a mechanical component such as a spring is subjected to repetitive or cyclical applications of stress levels much lower than the ultimate strength, it will fracture after a large number of repetitions of this stress.（4）Interchangeability means that identical parts must be interchangeable, i.e., able to replace each other, whether during assembly or subsequent maintenance work; without the need for any fitting operations.（5）A gear can be gripped axially between a shoulder on the shaft anda spacer, with torque being transmitted through a key.2、将下段英语翻译成汉语（10分）As we look around us w e see a world full of “things”, machines, devices, tools, things that we have designed, built, and used; things made of wood, metals, ceramics, and plastics. We know from experience that some things are better than others; they last longer, cost less, are quieter, or are ease to use. Ideally , however, every such itemhas been designed according to some set of “functional requirements”（5）当一个装置意外地失效后，通常需要进行研究工作，来找出失效的原因和确定可能的改正措施。

The engineering design component of a curriculum must include most of the following features : development of student creativity, use of open-ended problem statement and use of modern design theory and methodology, formulation of design problem statement and specification, consideration of alternative solutions, feasibility considerations, production process, concurrent engineering design, and detailed system descriptions. Further, it is essential to include a variety of realistic constraints such as economic factors, safety, reliability, aesthetics, ethics, and social impact.31、what’s the main meaning of message (1)?A) Engineering design is a systematic process B) materials engineer’s main workC) mechanical engineer’s has good idea D) electrical engineer’ main duty32、In the author’s opinion, the design process is very complex and should taken intoaccount many factors, from the message who should NOT join into the design team _______.A) environmentalists,B) sociologistsC) engineersD) Government officials33、From the message, we can know the meaning of words “ABET”(at line third paragraph)is _____.A) a set of accredits standardB) a kind of design methodC) a department of US government which responsible for engineering designD) A set of law34、It can be concluded from the passage that in the exercise and training of student,which character of the following is NOT included in the curriculum ______.A) creativityB) new materialC) ethicsD) economic factors35、The title of the message is ______.A) the roles of engineers in manufacturingB) the importance of mechanical designC) engineering designD) The process of machine designTEXT 2Working drawings are the complete set of standardized drawings specifying the manufactureand assembly of a product based on its design. The complexity of the design determines the number and types of drawings. Working drawings may be on more than one sheet and may contain written instructions called specifications.Working drawings are blueprints used for manufacturing products. Therefore, the set of drawings must:(a) completely describe the parts, both visually and dimensionally;(b)show the parts in assembly;(3)identify all the parts; and (4)specify standard parts. The graphics and text information must be sufficiently complete and accurate to manufacture and assemble the product without error.共 5 页第 2页(1) Detail drawings of each nonstandard parts.(2) An assembly or subassembly drawing showing all the standard and nonstandard parts in a single drawing.(3) A bill of materials (BOM).(4) A title block.A detail drawing is a dimensioned, multiview drawing of a single part, describing the part’s shape, size, material, and surface roughness, in sufficient detail for the part to be manufactured based on the drawing alone. Detail drawings are produced from design sketches or extracted from 3-D computer models. They adhere strictly to ANSI standards and the standard for the specific company, for dimensioning, assigning part numbers, notes, tolerances, etc.In an assembly, standard parts such as threaded fasteners and bearings are not drawn as details, but are shown in the assembly view. Standard parts are not drawn as details because they are normally purchased, not manufactured, for assembly.For large assemblies or assembled with large parts, details are drawn on multiple sheets, and a separate sheet is used for the assembly view. If the assembly is simple or the parts are small, detail drawings for each part of an assembly can be placed on a single sheet.Multiple details on a sheet are usually drawn at the same scale. If different scales are used, they are clearly marked under each detail. Also,when more than one detail is placed on a sheet, the spacing between detailsTEXT 3One principle aim of kinematics is to create (design) the desired motions of the subjects’ mechanical parts and then mathematically compute the positions, velocities, and accelerations, which those will create on the parts. Since, for most earthbound mechanical systems, the mass remains essentially constant with time, defining the accelerations as a function of time then also defines the dynamic forces as a function of time. Stresses, in turn, will be a function of both applied and inertial (ma) forces. Since engineering design is charged with creating systems which will not fail during their expected service life, the goal is to keep stresses within acceptable limits for the materials chosen and the environmental conditions encountered. This obviously requires that all system forces be defined and kept within desired limits. In machinery, the largest forces encountered are often those due to the dynamics of the machine itself. These dynamic forces are proportional to acceleration, which brings us back to kinematics, the foundation of mechanical design. Very basic and early decision in the design process involving kinematic principles can be crucial to the success of any mechanical design; a design which has poor kinematics will prove troublesome and perform badly.Any mechanical system can be classified according to the number of degree of freedom (DOF) which it processes. The system’s DOF is equal to the number of independent parameters which are needed to uniquely define its position in space at any instant of time.A rigid body free to move within a reference frame will, in the general case, has complex motion, which is a simultaneous combination of rotation and translation. In three-dimensional space, there may be rotation about any axis and also simultaneous translation which can be resolved into components along three axes. In a plane, or two-dimensional space, complex motion becomes a combination of simultaneous rotation about one axis (perpendicular to theplane) and also translation resolved into components along two axes in the plane41、Kinematics research focus on the following EXCEPT ______..A) accelerations B) forceC) positions, D) velocities42、From the passage that for the design engineer the first and most important is____A) the service life of a machine B) the materials chooseC) the degree of freedom D) kinematic principles43、An mechanical system has uniquely defined position in space at any instant of time that ___.A) It should has one DOFB) It should Has two DOFC) the DOF and the number of independent parameters should equalD) It should has any DOF as want44、 which one of the following is NOT TRUE _______?.A) A rigid body free to move in three-dimensional space may rotation about any axisB) A rigid body free to move in three-dimensional space is a simultaneous combinationof rotation and translationC) A rigid body free to move in three-dimensional space can be resolved into componentsalong three axesD) A rigid body free to move in three-dimensional space may has complex motion45、The best title for this passage would be _______.A) kinematics B) dynamicsC) kinematics and dynamic D) the important of kinematics共 5 页第3 页1．将下列英语句子译成汉语（共5小题，每小题2分）（1）A perfectly rigid or inextensible link can exist only as a textbook type of model of a real machine member.（2）Foundations should ensure the machine’s stiffness; shock absorption and isolation are secondary considerations.(3)Thus, if a mechanical component such as a spring is subjected to repetitive or cyclical applications of stress levels much lower than the ultimate strength, it will fracture after a large number of repetitions of this stress.（4）Interchangeability means that identical parts must be interchangeable, i.e., able to replace each other, whether during assembly or subsequent maintenance work; without the need for any fitting operations.（5）A gear can be gripped axially between a shoulder on the shaft and a spacer, with torque being transmitted through a key.2、将下段英语翻译成汉语（10分）As we look around us we see a world full of “things”, machines, devices, tools, things that we have designed, built, and used; things made of wood, metals, ceramics, and plastics. We know from experience that some things are better than others; they last longer, cost less, are quieter, or are ease to use. Ideally , however, every such item has been designed according to some set of “functional requirements” as perceived by thedesigners—that is, it hs been designed so as to answer the question,（5）当一个装置意外地失效后，通常需要进行研究工作，来找出失效的原因和确定可能的改正措施。
