摘　　要：本文提出了一种稳健的对冲压模具参数设计方法,以V形件冲压过程研究对象,采用有限元仿真软件ABAQUS建立了V形件冲压加工过程仿真模型,并利用田口方法,分析了所有建模因子对仿真模型的稳健性影响,找出最有利于提高模型稳健性的建模因子及水平设置.采用正交实验设计,就模具参数的稳健设计进行了分析,并以试验对本研究方法进行了验证.确认了在现有的仿真实验和试验水平下,本文提出的方法是可行的,结论是合理的.An alternate methodology on parameter robustness design for die in stamping process is proposed in this article. The V - shape stamping process was analyzed and the finite element simulation software ABAQUS was used to build the model. Taguchi method was used to make out a robustness design of V - shape stamping process. In Taguchi method, the solution to select the controllable factors and noise factors and their levels was analyzed. Orthogonal design was used to analyze the combination of controllable factors. With confirmation of practical experiments, it can be concluded that the design is reasonable.
