摘　　要：通过MATLAB和Simulink研究平面四杆机构及连杆点运动学仿真。用矢量法建立四杆机构及其连杆点的运动学模型,在Simulink仿真平台上建立其运动仿真模型,结合MATLAB进行编程分析,揭示连杆点及机构运动规律,仿真验证四杆机构的运动并对仿真参数进行优化设计。最后给出了满足Grashof条件的搅拌器曲柄摇杆机构验证实例。Kinematics simulation of four-bar linkage mechanism based on MATLAB and Simulink is researched. First, the kinematics model of four-bar lingkage mechanism and coupler point is established by vector method. Second, the motion simulation model is established in Simulink and programmed by using MATLAB. Motion of four-bar linkage mechanism is analysed and verified by using the simulation model to reveal the motion law of coupler point and lingkage mechanism, so the parameters can be optimized according to the simulation results. At last, verified example is given by using a crank-rocker mechanism of mixer satisfied the grashof condition.
