用有限元方法分析了U形槽弯曲成形过程中常用的几种减弹技术，包括圆弧打底技术、挤压模技术、扭压技术和运动技术。首先通过有限元模拟建立了各工艺回弹量与成形参数之间的关系，然后将优化分析与有限元分析相结合，找出了各工艺的最佳成形参数。
Several springback reduction techniques used in the U-channel bending processes were analyzed with the finite element method, which included arc bottoming, pinching die, spanking and movement techniques. The relationship between the amount of springback and the forming parameters in each technique was first established through finite element simulations, and then the optimization analysis was coupled with the finite element analysis to find the optimum forming parameters for each springback reduction technique.
