本文介绍了使用液压成形框架侧边护栏的成形模拟输出数据作为部件碰撞模拟的初始材料特性。描述了液压成形仿真模型，并与试验测量结果进行了相关性分析。方法开发形成和耐撞性分析之间的数据传输和现有系统的局限性确定。车架侧边护栏承受典型的碰撞载荷; LS-DYNA用于成形和碰撞模拟。厚度，加工硬化和残余应力的耐撞性结果的影响进行了量化;碰撞响应被认为是显着影响时，包括成型的影响。
This paper describes the use of forming simulation output data from a hydroformed frame siderail as initial material properties for crash simulation of the component. The hydroforming simulation model is described and correlated to test measurements. Methods developed to transfer data between forming and crashworthiness analyses are presented and the limitations of the existing systems identified. The frame siderail was subjected to a representative crash load; LS-DYNA was used for both forming and crash simulations. The effect of thickness, work hardening and residual stresses on the crashworthiness results is quantified; crash response is seen to be significantly affected when the effects of forming are included.
