bending spring-back

基本解释

In order to acquire the local bending spring-back accuracy of sheet metal strip of a progressive die design, the thesis aims to build ironing depth simulation model in a bending deformation zone.
为解决级进模具使用的带料上的局部折弯回弹的精度问题，本文建立了折弯变形区的过压量模拟模型。
The design of the die system of the carriage bending parts is realized: from technical calculating and spring-back rebuilding of die parts to structure design and assembling of the die system, etc;
系统实现了常见客车弯曲件的模具系统的设计：从零件的工艺计算、回弹重建到模具系统的结构设计、装配等；
From the comparison of the results, it is concluded that spring-back principle of minimum potential energy for straight beam formed by bending and its finite element methods are right.
结果证明了弯曲成形直梁回弹最小势能原理及弯曲成形直梁回弹有限元法的正确性。
