摘要 提出了一种变压边力优化设计方法 ,以抑制冲压件回弹变形、提高成形精度。基于数值模拟确定变压边力曲线中各设计变量 ,如不同区段压边力的大小、压边力变化时刻等的取值范围 ,并将正交试验设计方法引入到优化解的搜索过程中以提高优化过程的效率。将这种方法应用到一个实际轿车冲压件———仪表板支架的成形过程中 ,通过与数值模拟相结合 。 An optimization design method of variable blankholder force is put forward to improve forming accuracy of stamping parts. The ranging of design variables is determined by numerical simulation. Combining orthogonal design of experiment with FEM software, a proper blankholder force trajectory can be quickly acquired. Finally, the method is applied to the forming process of an actual auto panel.
