| 摘 要： | 用正交试验设计法对影响"L"形板料弯曲回弹的相关因素进行优化设计.借助正交试验设计方法安排试验方案,利用ANSYS/LS-DYNA的数值模拟得出各组方案中不同因素组合下的回弹量;借助直观分析和方差分析,分析影响回弹的主效应因素及各因素较优的取值范围,最后对各因素水平的最优组合进行研究.仿真结果表明,因素水平的最优搭配可以使"L"形板料弯曲成形回弹达到最小值.

| Abstract: | The related springback factors influencing L-shaped sheet bending was optimally designed with a method based on orthogonal experiment.By using this method,experiment scheme was arranged.The springback value due to different factors combined as arranged in the scheme was obtained by using ANSYS/LS-DYNA numerical simulation.By using visual analysis and variance analysis,the factor that had primary influence on the springback was analyzed,and assignment range of less optimal factors that had less influence on ... |
