摘　　要：本文先用解析法建立六杆机构运动特性的数学模型,利用Excel求出曲柄在不同位置时,导杆的运动变化情况。然后基于COSMOSMotion的运动仿真,绘出导杆的运动曲线,并将解析法计算值与仿真结果进行比较,以验证解析法数学模型的正确性。最后对仿真误差的来源进行了分析。Firstly the numerical model of kinematics characteristic of a planar six-bar mechanism was built with analytic method, the kinematics change values of the guide-bar was solved when the crank was in different position by using MS. Excel, and then the motion curve of the guide-bar was obtained based on COSMOSMotion, the calculation value of analytic method was compared with the simulation result in order to check the correct of the numerical model with analytic method. Lastly the source of simulation error was analysed.
