基于数值模拟和回归正交设计的AA5754铝合金温成形回弹特性
Springback analysis of warm forming for aluminum alloy AA5754 by numerical simulation method in conjunction with regression orthogonal design
摘要
Abstract
Based on the split-ring experiment for cylindrical drawing cups, a regression model of relationship between springback and process parameters, including initial forming temperature of blank, friction coefficient, blank holder force, die radius and clearance between punch and die, was established for warm forming of aluminum alloy by numerical simulation method in conjunction with the regression orthogonal test. The effect of process parameters on springback was investigated, and the optimal combination of process parameters was determined. The regression model was applied to predict the springback, whose results were compared with those of test and numerical simulation at four kinds of temperatures. The results show that with high significance and fitting degree, the regression model is reliable.关键词
