基于铰链四杆机构运动学的解析法及ADAMS仿真

KINEMATIC ANALYSIS OF THE PLANAR FOUR BAR LINKAGE MECHANISM BASED ON ANALYTIC METHOD AND ADAMS SIMULATION

目前研究铰链四杆机构运动规律的主要方法有解析法和ADAMS仿真,这两种方法都能得到该机构的运动规律,下面将采用解析法中的复数矢量法,对曲柄角速度恒定的铰链四杆机构的运动规律进行推导,并采用MATLAB求解,绘出连杆和摇杆的运动规律图;同时通过ADAMS仿真进行对比验证,从而比较两种方法的结果.

At present, the main method for kinematic analysis of the Planar Four Bar Linkage Mechanism are analytic method and ADAMS simulation. Both of them can get the motion law of the machinery. On the one hand this paper uses the analytical method to deduce the motion law of the machinery, and solve it by MATLAB, then plot the motion of linkage and racker. On the other hand, uses ADAMS simulation to compare the results.
