阶梯盒件拉深成形有限元分析与正交优化

Finite Element Analysis and Orthogonal Optimization of Ladder Box Pieces Deep Drawing Forming

分析了影响阶梯盒件成形性能的主要因素:压边力、拉延速度、凹模圆角半径以及阶梯转角。通过Dynaform软件对阶梯盒件拉深成形进行了单因素分析,得到了合理的压边力、拉延速度、凹模圆角半径以及阶梯转角取值范围。采用正交试验法对以上因素进行了多因素的正交优化分析,得到了最优的参数组合。

The main factors affecting the formability of the ladder box pieces were analyzed, such as BHF（blank holder force）,drawing speed, die radius and ladder corner. The single factor analysis of deep drawing forming of the ladder box pieces was carried out by Dynaform software. And appropriate BHF, drawing speed, die radii and the range of ladder corner were obtained. Orthogonal optimization analysis of multi-factors of above factors was carried out by adopting the orthogonal experiment method. Optimal parameter combination was gotten.
