摘要：

为了提高冲压成形的工件质量、模具的使用寿命，提出了高效成长郊狼算法的机械压力机肘杆机构优化方法。介绍了三角形肘杆式机械压力机的工作原理，建立了机械压力机的运动学模型和优化模型。在郊狼算法的基础上，给出了种群最优参与的高效成长方法和静态贪心策略，从而提出了高效成长郊狼算法的优化模型的求解方法。同时,使用郊狼算法和高效成长郊狼算法求解优化模型，高效成长郊狼算法的压力角减少了36.16%，提高了传动效率；滑块加速度峰值减小了约一半，提高了模具的使用寿命；滑块速度波动量减小了约一半，提高了冲压成形的工件质量。

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.
