基于响应曲面的时效成形材料参数修正

摘要

A modified solution of material parameters is obtained by solving simulation error response function for material parameters, which is established by response surface methods combined with uniform design, in order to improve finite element analysis precise for springback in creep age forming. The simulation results with the modified solution are in accord with experimental results.%为了提高时效成形中回弹现象的有限元仿真精度,使用均匀试验设计结合响应曲面设计的方法,建立了仿真误差对于材料参数的响应函数,求解出材料参数的修正解.以此法得到的仿真结果与试验结果相吻合.
