前言/序言
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�瞕imensional 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本教材是為機械工程專業的學生學習機械原理課程或專業英語編寫的。
本教材於2012年齣版後,一些學校選其作為本科生機械原理課程的中文教材,教學時講授中文,英語內容作為參考;一些學校選其作為機械原理課程的英文教材,教學時講授英文,中文內容作為參考;一些開設雙語教學的學校,選其作為本科生的英漢雙語教學機械原理課程教材,教學時有時用英文講授,有時用中文講授,中、英文內容可用來對比和參考。一些學校選其作為外國留學生的機械原理課程教材,也有一些學校選其作為國際班的機械原理課程教材。本教材不但使學生獲得機械原理的基本知識,還可以提高學生英語的口語和寫作能力。
經過幾年的使用,根據作者自查和用戶意見反饋,對其進行瞭修改、補充和完善,如在平麵連杆機構的綜閤內容中,引入瞭新方法,但缺少例題佐證。所以,本次修改增加瞭相應例題;在說明槽輪機構的運動特性時,采用瞭六槽槽輪代替四槽槽輪,這樣就容易理解主動銷輪和從動槽輪的轉角關係,更容易理解槽輪機構的運動係數。在機械平衡設計一章中也增加瞭例題。
本次修訂還更正瞭一些文字錯誤和語法錯誤,並引入瞭二維碼技術,讀者隻要用手機掃描插圖旁的二維碼,就可以觀看相應機構的動畫,增強瞭本教材的可讀性。
北京工業大學的何岑成老師參與瞭本次修訂工作和英語教材的編審工作,北京理工大學的趙嘉珩為本教材增編瞭例題。
感謝我的博士生團隊為本書的修訂所做的工作。
由於編者水平有限,書中難免存在錯誤和疏漏之處,歡迎廣大讀者批評指正。
張春林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
