【摘要】 利用Autoform软件对汽车左、右侧围内板前段进行模拟分析,在压边力、拉深筋等因素已确定的条件下,对板料成形过程中的各个工序进行数值模拟,通过对所得到的成形极限图、厚度减薄率等性能参数的分析,判定各成形工序的合理性,最终确定最优的成形工艺。更多还原

【Abstract】 On the condition of the specified blank-holder force and drawbead,each proce dure in the forming process of the forepart of a side-frame inner panel was simulated us ing the software Autoform.Through analyzing the performance parameters obtained,such as forming limit diagram(FLD) and thickness thinning ratio,the reasonability of each form ing procedure and the optimum forming process were determined.更多还原
