本書是在臺(tái)灣學(xué)者顏鴻森、吳隆庸先生所著《機(jī)構(gòu)學(xué)》第4版的基礎(chǔ)上整理而成的簡(jiǎn)體中文版。原著是作者基于30年來(lái)在國(guó)內(nèi)外大學(xué)、研究機(jī)構(gòu)和工業(yè)界教學(xué)、研究、服務(wù)的經(jīng)驗(yàn),在考慮機(jī)械工程及相關(guān)領(lǐng)域的教學(xué)環(huán)境和大專院校相關(guān)課程的學(xué)時(shí)的基礎(chǔ)上撰寫而成的。
本書內(nèi)容分為11章,包括:緒言、機(jī)構(gòu)的組成、確定性運(yùn)動(dòng)、機(jī)構(gòu)的運(yùn)動(dòng)、連桿機(jī)構(gòu)、位置分析、速度分析、加速度分析、凸輪機(jī)構(gòu)、齒輪機(jī)構(gòu)、其他機(jī)構(gòu)。書中對(duì)于基本原理的介紹,都配有應(yīng)用實(shí)例說(shuō)明。此外,本書習(xí)題經(jīng)過(guò)了精心設(shè)計(jì),不但能方便學(xué)生了解教材內(nèi)容,更合乎生活化與實(shí)用化的要求。
由于內(nèi)容和編排體系與大陸機(jī)械原理教材類似,所以本書可以作為大陸本科機(jī)械原理課程的教材,也可作為相關(guān)專業(yè)的研究生和科研人員的參考書。
