摘要:
利用冲压成形后便于获取的板料厚度值作为响应构造遗传算法中的目标函数,结合有限元法和遗传算法,提出一种快速反求冲压成形中材料性能参数的方法.在有限元模拟中,使用反求后参数获取的板料厚度值和实际冲压中的板料厚度值吻合度非常理想,验证了该方法应用于冲压成形的快速、准确和有效性.
Abstract:
The thickness value which is easily measured from the stamped parts is selected as a response to construct the objective function of genetic algorithm. Combined with the finite element method and the genetic algorithm, a method for rapid inverse identification of the material performance parameters in sheet metal forming is proposed. The sheet thickness value obtained through reverse parameter in the finite element simulation agrees well with the actual stamping result. It is proved that the inverse method is effective, reliable and accurate.
