Kinematic simulation analysis of mechanism for six-linkage mechanical press based on Simulink

Taking the mechanism of six-linkage mechanical press as research object,the mathematical model with kinematic analysis has been established to the mechanism.Aiming at the shortage of graphic solution and analytical methods, a new solution of implicit equations by use of Simulink has been put forward.The curves of slide displacement,velocity, and acceleration for press have been drawn quickly and accurately.Meanwhile,the linkage mechanism has been optimized by modifying simulation parameters, which provides reference for the design of multi-linkage mechanical press.The simulation results show that the method has advantages of high efficiency, intuition, and high accuracy.
