为改善铝合金板材冲压后的回弹缺陷,以某笔记本电脑后盖板为研究对象,基于Creo Parametric软件构造了板材和模具的几何模型,通过LS DYNA有限元软件建立仿真模型,利用Quantum XL数据分析软件设计了压边力、模具间隙和冲压速率三个关键因子的响应曲面试验,得到了盖板整体最大回弹量、截面轮廓回弹角度两个响应值的二阶回归模型,并由响应面模型求解出最优参数组合为:压边力11kN,模具间隙0.7mm,冲压速率1000mm/s.
Optimization of Process Parameters for Stamping Forming Aluminum Alloy Enclosures Based on Response Surface Method
To reduce the spring back defect of stamping aluminum alloy sheet,a laptop enclosure was used as an object and geometric models of the sheet metal and dies are constructed using Creo Parametric soft-ware.A simulation model is established using LS-DYNA finite element software and response surface experi-ments for blank holder force,die clearance,and stamping speed are designed using Quantum XL software which leads to the development of quadratic regression models for two responses:the maximum spring back and the angular deviation of the given section contour.The optimal parameter combination is determined as a blank holder force of 11kN,die clearance of 0.7mm,and stamping speed of 1000 mm/s.
