【摘要】 本文针对桑塔纳2000塑轿车后翼子板尾车灯部位在实际生产中存在的问题,用AutoForm对其拉延过程进行了仿真。根据仿真结果,后翼子板尾车灯部位在拉延时加深2mm是完全可行的。本文的工作表明,用专业的有限元软件可以快而且正确地分析出覆盖件特征部位在冲压成形过程中的变形行为,对实际的模具设计制造和模具维修具有指导意义。更多还原

【Abstract】 The simulation of drawing process of Santana 2000’s rear fender has been completed by AutoForm, a famous finite element (FE) software for-sheet forming simulation, to analyze the production problems exist in the rear light area. According to the simulation results, it is feasible to increase 2mm in depth at the rear light area of rear fender. The present work indicated that the forma-bility of autobody panel can be exactly predicted by professional finite element software, as which give instruction for die-making and die-adjusting.更多还原
