采用数值模拟的方法,分析了大型薄壁冲压件(汽车前上梁外板)成形过程的影响因素,优化了成形极限和成形厚度,获得了汽车大型薄壁件冲压成形的最优工艺参数,为实际生产提供了理论支持。
The influencing factors of the forming process of the large thin-walled stamping parts (the outer beam of the front beam) were analyzed by numerical simulation. The forming limit and the forming thickness were optimized. The optimum process parameters for the stamping of large- For the actual production provides a theoretical support.
