Capter1Introduction-机械原理.ppt

Course Name: The Theory of Machines and Mechanisms ;1.1 Study content of the course (课程学习内容);Machinery: all kinds of the machines and mechanisms. 机械：机器和机构的总称。 Mechanism: a motional equipment which is used to transfer and change the motion and force. 机构：是指一种用来传递与变换运动和力的可动装置。 Machine: one of the machinery carrying out the motion, could be used to transform and transfer the energy, materiel and information. 机器：是指一种执行机械运动装置，可用来变换和传递能量、物料和信息。;Capter1 Introduction; The functions and profiles of machines may be quite different, but the mechanisms used in them are often the same. This situation is similar to the combinations of the five-price puzzle. With only seven plates, many different patterns can be constructed. The most content of this book is for “analysis” and “synthesis” of some commonly used mechanisms. 虽然功能和外形看起来相差很大，其实采用的机械装置却基本相似。这种情形类似于五大模块的组合，采用这几种模块结构可以构造许多不同的部件。因此，本门课程学习主要内容在于对常见机构的分解和合成。;Capter1 Introduction; This should lead to the ability to choose machinery motion pattern, analysis and synthesize mechanisms and develop designs for practical working machinery. Therefore the knowledge to be obtained from this textbook is a fundamental and very useful to analyze existing machines and design new ones. 通过这门课程的学习，可以很好地引导学生进行机构运动形式的选择、运动装置的分析，机械装置的设计。因此，为了更好地分析，认识已有机构，设计新的机械装置，学好这门课程非常有用。 ;Classification of Machine: ;Transforming Materials ;Transporting Machinery;Transform Information? ;Capter1 Introduction;First: understand the concepts and principle clear, grasp the common methods about the “analysis” and “synthesis” of mechanisms. 第一点：为了学好本课程，就要着重注意搞清基本概念，理解基本原理，掌握机构分析和综合的基本方法。 Second: you had better train the ability to analyse and solve the problems with what you have learned within study process. 第二点：在学习过程中，要注意培养运用自己所学的基本理论和方法去分析和解决工程实际问题的能力。;Third：you should train yourself the ability to consider the condition roundly and the strict and dedicated study attitu
