机械原理英汉双语第2版_张颖张春林_9787111548836

本教材是根据教育部提出的“面向21世纪教学内容和课程体系改革计划”的基本思想，以满足新世纪教学改革和教材改革为指导思想进行编写的，全书以培养机械系统方案创新设计能力为目标，在内容编排上贯穿了以设计为主线的思想，将全书内容进行了有机的组合，共分为十章，主要内容包括；机构的结构分析，机构的性能分析，平面连杆机构、凸轮机构、齿轮机构、轮系及其设计，其他常用机构及其设计，机构系统动力学设计，机械系统的运动方案及机构的创新设计。为了方便读者掌握重点内容和拓宽知识面，每章后均有“知识要点与拓展”的内容。本书在注重培养学生逻辑思维能力的同时，还配有多媒体教学软件，为开发学生手形象思维能力创造了条件。本书主要作为普通高等院校机械类专业的教学用书，也可作为非机械类专业学生及有关工程技术人员的参考书。

This book has been written for mechanical engineering students who are beginning to study the theory of machines and mechanisms or professional English.Since the book was published in 2012, some universities take it as Chinese textbook of theory of machines and mechanisms for undergraduates, some universities take it as English textbook of theory of machines and mechanisms for undergraduates, some universities take it as bilingual education textbook of theory of machines and mechanisms, some universities take it as foreign students textbook of theory of machines and mechanisms,and some universities take it as international class students textbook of theory of machines and mechanisms. Such students will have acquired a set of mechanical engineering knowledge and the ability to use English language to express themselves in spoken and written forms.This edition has been influenced by changes in engineering education, suggestions by colleagues and users, and the author’s checkup.The major revisionary works for publishing this new edition are as follows.Effort has been made to remove all sorts of errors and misprints as far as possible.We adopt a simple mathematical manner for easy comprehension by students in Chapter 5, but there are not any examples to describe the new methods. So many examples have been added in Chapter 5.Geneva wheel with 6 slots will be more helpful to understand the action ratio, so we use a Geneva wheel with 6 slots instead of Geneva wheel with 4 slots.Some of examples have been added in Chapter 13 too.Twodimensional codes are added in this edition to describe the mechanisms animated figures.I acknowledge the efforts of professor He Cencheng of Beijing University of Technology for revisionary and compiled works for this edition.Zhao Jiaheng of Beijing Institute of Technology compiled some examples.Finally, I make an affectionate acknowledge to my PhD doctors team for their support.I am grateful to all readers who pointed out errors and mistakes of the previous edition and gave valuable suggestions.Zhang Chunlin本教材是为机械工程专业的学生学习机械原理课程或专业英语编写的。

本教材于2012年出版后，一些学校选其作为本科生机械原理课程的中文教材，教学时讲授中文，英语内容作为参考；一些学校选其作为机械原理课程的英文教材，教学时讲授英文，中文内容作为参考；一些开设双语教学的学校，选其作为本科生的英汉双语教学机械原理课程教材，教学时有时用英文讲授，有时用中文讲授，中、英文内容可用来对比和参考。一些学校选其作为外国留学生的机械原理课程教材，也有一些学校选其作为国际班的机械原理课程教材。本教材不但使学生获得机械原理的基本知识，还可以提高学生英语的口语和写作能力。

经过几年的使用，根据作者自查和用户意见反馈，对其进行了修改、补充和完善，如在平面连杆机构的综合内容中，引入了新方法，但缺少例题佐证。所以，本次修改增加了相应例题；在说明槽轮机构的运动特性时，采用了六槽槽轮代替四槽槽轮，这样就容易理解主动销轮和从动槽轮的转角关系，更容易理解槽轮机构的运动系数。在机械平衡设计一章中也增加了例题。

本次修订还更正了一些文字错误和语法错误，并引入了二维码技术，读者只要用手机扫描插图旁的二维码，就可以观看相应机构的动画，增强了本教材的可读性。

北京工业大学的何岑成老师参与了本次修订工作和英语教材的编审工作，北京理工大学的赵嘉珩为本教材增编了例题。

感谢我的博士生团队为本书的修订所做的工作。

由于编者水平有限，书中难免存在错误和疏漏之处，欢迎广大读者批评指正。

张春林Along with the rapid development of science and technology, the higher education will speed up internationalization. So it is necessary to compile a compatible textbook which not only has Chinese feature, but also makes for globalization. This is a new object that the teaching reform of China s higher education is faced with. On the one hand, the direct adoption of the foreign classical textbooks does not suit the actual state of our teaching in Chinese universities; on the other hand, the Chinese language textbooks cannot be brought in line with the international practice. Therefore, we will compile a bilingual textbook on “theory of machines and mechanisms” with the support of China Machine Press.This book is based on the basic teaching r
