摘  要
本機(jī)構(gòu)資源庫是在綜合了前人智慧的基礎(chǔ)上實現(xiàn)的，可供機(jī)械工程及其他技術(shù)人員在改造老產(chǎn)品和開發(fā)新產(chǎn)品設(shè)計時參考使用，可以幫助設(shè)計者精確選型，縮短設(shè)計周期，降低設(shè)計成本，這對加快創(chuàng)新開發(fā)和推動技術(shù)進(jìn)步無疑具有重要意義。
本論文就是建立在對一些平面機(jī)構(gòu)或機(jī)械產(chǎn)品結(jié)構(gòu)簡圖的基礎(chǔ)上，根據(jù)自己擬定的結(jié)構(gòu)參數(shù)，采用SolidWorks進(jìn)行三維建模和零件裝配，然后采用COSMOSMotion進(jìn)行運動和動力仿真分析，完成一些典型的連桿、凸輪、齒輪、螺旋等機(jī)構(gòu)的設(shè)計與仿真，從而驗證、修改、優(yōu)化設(shè)計方案，使得以前需要組織研究團(tuán)隊，進(jìn)行復(fù)雜設(shè)計計算，制造物理樣機(jī)驗證結(jié)果的設(shè)計過程大大簡化。
第一章主要闡述了機(jī)構(gòu)設(shè)計的概念及方法和物理樣機(jī)及其技術(shù)；第二章簡單地介紹了SolidWorks軟件；第三章針對步進(jìn)送料機(jī)構(gòu)和凸輪機(jī)構(gòu)，詳細(xì)介紹了機(jī)構(gòu)的建模、裝配與仿真；第四章闡述了各機(jī)構(gòu)的裝配與仿真模型,主要包括飛機(jī)起落架的擺動導(dǎo)桿機(jī)構(gòu)、起重機(jī)的曲柄滑塊機(jī)構(gòu)、輪子轉(zhuǎn)向的螺旋連桿機(jī)構(gòu)、手爪平行開閉的機(jī)械手、簡易振動機(jī)、鋸條的凸輪機(jī)構(gòu)、增大行程的連桿齒輪組合機(jī)構(gòu)、由曲柄滑塊驅(qū)動的螺旋連桿機(jī)構(gòu)、槽形凸輪驅(qū)動的直線運動機(jī)構(gòu)、縫紉機(jī)的導(dǎo)桿球面機(jī)構(gòu)等。

Abstract
 The resource bank is a synthesis of the wisdom of our predecessors on the basis of the for mechanical engineering and other technical personnel in the transformation of old products and the development of new products using the reference design, can help designers accurate selection, shorten the design cycle, reduce design costs, This innovation to accelerate the development and promoting technological progress is undoubtedly of great significance.
 This paper is based on the basis of some plane mechanisms or mechanical products' schematic structure. According to the structure drawn up by the parameters, use SolidWorks 3D modeling and assembly parts. Then use COSMOSMotion movtion and dynamic simulation analysis, complete the typical mechanisms of the link, cams, gears, spiral and other mechanisms design and simulation, then test, modify and optimize the design, made before the need to organize a group to study complex design and calculation, Manufacturing physical prototype test results greatly simplify the design process.
 Chapter 1 mainly elaborates the concept and method of mechanisms’ design, and physical prototype and its technique; Chapter 2 introduces the software of SolidWorks in brief; Chapter 3 aims at a Step-feed mechanism and cam mechanism, introducing mechanism to set up a mold and assemble and simulation in detail; Chapter 4 elaborates each mechanism of assemble and simulation model, mainly include the airplane rises and falls of the swing lead the crank of pole mechanism, the crank and block mechanism of cranes, the screw connect pole mechanism of wheel steering, the hand-claw parallelism open to shut of machine hand, the simple vibration mechanism, the cam mechanism of saw, the enlarging a route of travel of the combination of pole gear mechanism, the crank and block mechanism of the screw connect pole mechanism, slot form the cam drive of the straight line mechanism, the spherical pole mechanism of sewing machine etc..
