【摘要】 金属成形数值模拟是金属塑性加工领域的热门课题之一，在工业中发挥着巨大的作用。 本文运用非线性有限元软件ANSYS／LS-DYNA对汽车落地骨架零件进行了冲压成形的数值模拟，得出了毛坯外形，预测了成形过程中板料壁厚变化和可能出现的起皱、破裂现象，通过回弹模拟，预测了回弹趋势，获得了该类零件成形所需要的工艺参数，对实际生产具有一定的指导作用。 本文还以软件工程的开发模式为依据，结合MVC模式的软件架构设计思想，对SGI工作站下的板成形专用有限元软件包SHEET-FORMING前处理器的微机移植作了人机界面的软件架构设计。更多还原

【Abstract】 The numerical simulation technology of metal forming is one of the pop domain in metal plastic forming, play a great effect in industry.In this paper, by using non-linear finite element software, ANSYS/LS-DYNA, simulate a forming of auto fall to ground skeleton part, get the contour of the semi-finished product, forecast the change of the blank thickness and the probable wrinkling, cracking, and from the simulation of the spring-back, obtain the spring-back tendency. So, get technology parameters, which are inextricable to forming production. All these will pose great significant to production in theory and reality.Also in this paper, abide by the software engineer develop model, combining with the software frame thinking of MVC model, give the design model of the pre-processing transplanting which from SGI workstation to personal computer of the SHEET-FORMING, a non-linear finite element analysis software.更多还原
