使用ANSYS分析软件,建立了车轮轮辐冲压系统的仿真模型,对翻边工序进行了有限元模拟并分析了成型后轮辐等效应力分布,探究了冲压翻边高度、坯料屈服强度以及坯料厚度对轮辐成型的影响. 模拟结果表明,最佳工艺参数为:坯料屈服强度490 MPa,翻边高度16 mm,板厚4.2 mm,在此工艺条件下,轮辐零件圆孔翻边开裂现象得到有效控制,开裂率下降到0.01%.

Based on the simulation model established for the spokes of punching system by ANSYS software, the flanging process was simulated with finite element method, and the distribution of equivalent stress was analyzed. The influences of the punching flanging height, yield strength and thickness of the plate on the formation of spokes were discussed. The results show that the optimal process conditions are as follows:yield strength of 490 MPa, the flanging height at 16 mm, and material thickness of 4. 2 mm. Under these conditions, the cracking rate decreased to 0. 01%, resulting in the flanging cracking of spoke parts effectively controlled.
