Kinematic Analysis of the Planar Four Bar Linkage Mechanism Based on MATLAB

In this paper, the four bar linkage Mechanism was studied. On the basis of the kinematic analysis of the mechanism, a mathematical model was established and a system for the kinematic analysis of the mechanism was developed with MATLAB/GUI. In the system, when the original piece of the mechanism was turning around, once the parameters of the components of the four bar linkage mechanism and the angular velocity of the original moving piece were entered to the text edit boxes of graphical interface, the change law curves of the displacements, the speeds and the accelerations of the followers can be output quickly.
