摘　　要：以平面四杆机构为例,采用向量法、投影法、求导法建立了该机构的位移、速度和加速度求解方程,并将其转化为适于Matlab计算的矩阵模型.基于Matlab编制了相应的M函数计算模块,利用计算机解出了该机构的运动参数,并将计算结果可视化.结果表明:利用Matlab解决运动学计算问题快捷、准确,为处理类似计算提供了有效的参考.Taking the planar four-bar mechanism as an example,the kinematics equations（including displacement equations,velocity equations and acceleration equations） are established with the help of vector method,projection method and derivation method.These equations are converted to matrix models suitable for Matlab calculation.Its M-function calculation module is made up.The kinematic parameters of the mechanism system are solved,and the visualization result is obtained.The results show that this method is rapid and accurate and it provides an effective reference for the calculation of the similar problems.
