摘　　要：针对拉延成型过程易出现的潜在缺陷,选取凸凹模间隙、拉延筋作用力和压边力3个重要工艺参数作为影响因素,采用Box-Benhnken法设计响应曲面试验,建立工艺参数与最大减薄率和最大变厚率之间的响应面模型;通过响应面模型得到最优参数组合,即凸凹模间隙为1mm,拉延筋作用力因子为0.36,压边力为350kN。采用优化参数组合进行试模,试模结果与仿真结果的误差均小于3%,吻合较好,表明基于响应面法对工艺参数进行优化的方案切实可行,为板料拉延成型的优化提供1种方法。For the potential defect produced in drawing progress, the response curved surface test was designed based on Box- Benhnken method by choosing the three important process parameters like the gap between punch and die, the equivalent force factor of drawbead and the blank-holder force as the key influencing factors. And the response surface parameters and the max thinning rate and the max thickening rate of seat support plate was establisheters were obtained, which are 1mm for the gap between the punch and the die, 0. 36 for the equivalent force factor of the draw- bead, and 305 kN for the blank holder force. These optimal stamping parameters prove to be less than 3 % in error in comparison with the simulation results indicating a good agreement between physical and numerical data. to optimize the process parameters by using the response surface method, which provides an effective method fof drawing formability for sheet metal.
