【Abstract】 On the basis of analyzing the necessity of the simulation of the process of PLC control to mechanical press,the essentiality of the realization the cartoon of the moving process of crank link slide mechanism on microcomputer display unit is explicitly pointed out. Furthermore, in the light of the theoretically analyzing characteristics of the kinematics and the dynamics of crank link slide mechanism, programming with VB, it’s studied how to figure out the space position for all components of crank link slide mechanism, and how to realize the cartoon of the variety function curves between the slide displacement, velocity, acceleration, torque of the crank and the corner of crank on microcomputer display unit, and how to realize the four operation criterions and how to dispose the relative buttons on the microcomputer interface.更多还原
