| 摘 要： | 板料冲压成形过程中的回弹是卸载过程产生的反向弹性变形,是一种普遍存在的物理现象.目前,越来越多的商业化CAE软件实现了金属薄板冲压成形过程中的回弹模拟,但是回弹模拟精度仍然是数值模拟的难点.本文详细分析了影响回弹模拟精度的主要因素,总结了回弹模拟及补偿技术国内外发展现状.这对制定合理的冲压工艺方案,并在模具设计过程中,考虑回弹的关键因素,以便修正模具尺寸,补偿回弹误差,具有重要的实际意义.

| Abstract: | Springback in sheet metal forming is the reverse elastic deformation during the process of unloading process, which is a widespread physics phenomenon. At present, more commercial CAE software could simulate the course of springback during the sheet metal stamping process,but the simulation precision is still difficult for the numerical simulation. The main factors which impact the simulation accuracy of springback have been analyzed in the text in details. The development of simulation and compensation tec... |
