摘　　要：提出了一种建立板料成形压边力窗口的简易方法,并以TRIP600盒形件为例,通过数值模拟,建立其压边力成形窗口,进而采用均匀设计法对压边力加载曲线进行了优化。结果表明,均匀设计法能较好地满足板料成形中的多因素多目标优化,且优化后零件成形质量得到了提高。A simple method was proposed to establish the blank-holder force （BHF） window of sheet forming. And taking a TRIP600 rectangular box as an example, its BHF forming window was built by numerical simulation, in which the BHF loading curve was optimized by the uniform design method. The results show that, the uniform design method can well satisfy the need of optimization with multi-factors and multi-objectives in sheet forming, and the quality of the part is improved after optimization.
