| 摘 要： | 将确定性优化方法用于板料包边设计.汽车板料包边仿真中变形区域小导致有限元模型在变形区域的网格很小,模型计算时间太长.本文针对影响板料包边后边界缩进较大的3个参数,建立目标函数的径向基函数近似模型,并用确定性优化方法对近似模型进行优化,近似模型计算效率高,提高了优化方法计算效率,使板料包边的优化设计成为可能,并为生产中的汽车板料控制包边后的边界缩进提供了一种新的思路.

| Abstract: | Optimzation methods are applied to sheet metal hemming.For the determination of parameters that influence the roll-in,an approximation Hemming model is proposed,to be used with optimization methods.The small area of sheet metal hemming lead to low efficiency,while the approximation hemming model can solve the problem,which make hemming model optimization possible.And the approximation hemming model based certain optimization method offer a new method to control the roll-in in hemming. |

| Keywords: | hemming roll-in certain optimization radial basis function approximation model |
