在火箭发动机弯曲模设计过程中,无法定量地确定产品零件的回弹量,因此就无法较为准确地设计工装的结构尺寸,使其能够一次冲压成功.运用ABAQUS有限元分析软件,建立冲压模仿真分析模型,采用隐式动力学计算方法,模拟阳模的"冲压"、"停留"、"复位"动作,并集成Isight优化软件,以产品图样尺寸为优化目标,对给定的参数进行优化,进而得出阴阳模的结构尺寸,为弯曲模设计提供指导.%Because the amount of springback of product parts can not be determined quantitatively in the process of bending die de-sign,it is impossible to design the structure size of the bending die to stampit successfully at the first time. In this paper, the ABAQUS finite element analysis software is used to establish the true analysis model of the stamping simulation,and the implicit dy-namic calculation method is used to simulate the"stamping","stay","back"action. And meanwhile, the Isight optimization soft-ware is used to take the product size in the drawing as the optimization object and the given parameters are optimized to obtain the structure size of formpiston and female die. A good guidance is provided for the bending die design.
