Abstract：

In order to improve the quality of stamping workpiece and the service life of die, the optimization method of elbow-bar mechanism for mechanical press based on efficient growth coyote algorithm was proposed. Then, the working principle of triangle elbow-bar mechanical press was introduced, and the kinetics model and the optimization model of mechanical press were built. On the basis of coyote algorithm, the efficient growth method and static greedy strategy of optimal population participation were given, so that the solving method of optimization model based on efficient growth coyote algorithm was put forward. At the same time, the coyote algorithm and the efficient growth coyote algorithm were used to solve the optimization model. And the pressure angle of the efficient growth coyote algorithm is decreased by 36.16% which improves the transmission efficient. Furthermore, the peak value of slider accelerate decreases by about half which improves the service life of die, and the vibration of slider speed decreases by about half which improves the quality of stamping workpiece.
