摘要：

借助Dynaform软件，通过与实验结果对比，较准确地建立了某公司生产的发动机隔热罩冲压成形仿真模型。在此模型基础上，采用BBD设计安排实验，以冲压工艺参数为自变量，最大减薄率和起皱率为因变量，分别建立了工艺参数与最大减薄率和起皱率的二次多项式响应面模型，并对两个模型进行优化。以最大减薄率未优化响应面模型为约束，起皱率未优化响应面模型为目标函数，以及最大减薄率优化响应面模型为约束，起皱率优化响应面模型为目标函数，分别对工艺参数进行优化。结果显示，优化后的隔热罩仿真模型最大减薄率和起皱率控制在较好范围，且优化响应面模型的结果更优。

Compared with the experimental results, the accurate simulation model of forming an engine heat shield was established by Dynaform. Based on the model, the experiments were arranged by Box-Benhnken design. Furthermore, the process parameters were chosen as independent variables with the wrinkling rate and the maximum thinning rate defined as response values. The two order polynomial response surface models of the process parameters with the maximum wrinkling rate and with the maximum thinning rate were established respectively and were optimized by Design-Expert. Then, the maximum thinning rate without optimizing the response surface model was taken as the constraint condition and the rate of response surface without optimizing the wrinkling model was defined as objective function. After that, the maximum thinning rate optimizing response surface model was taken as the constraint condition and the rate of response surface optimizing wrinkling model was defined as objective function. Parameters of the above two situations were optimized respectively. Finally, the maximum thinning rate and wrinkling rate could be controlled in a certain range by the heat shield model optimized process parameters, and the results of optimized response surface model are better.
