【摘要】 采用有限元分析软件ANSYS,基于弹塑性有限元理论建立有限元模型,对汽车板件冲压连接过程进行了模拟。研究了冲压连接模具参数和不同板厚组合方式对互锁值c和颈厚值n的影响规律,并给出了模具参数选用的一般范围及不等厚板的最佳组合方式。试验表明,模拟结果与试验结果吻合较好,证明了利用有限元模拟方法对冲压连接的连接效果进行预测是可行的。更多还原

【Abstract】 Based on the elastic-plastic FE theory,the Punching Bonding process of the automobile sheets is simulated by using ANSYS analysis software in this paper.The effects of the punching bonding die parameters and different sheets thickness combination on the interlock parameters c and neck thickness n are mainly analyzed,the general range of die parameters selection and the optimal combination mode of different thickness sheets are presented.The tests show that simulation results agreed well with the tests,the prediction of punching bonding effect by FE simulation method is feasible.更多还原
