摘要：

将5754铝合金自冲铆接成形的模具磨损作为分析对象，基于Archard理论磨损模型与Deform-3D软件，建立两层2 mm 料厚的5754铝合金自冲铆接安装模具磨损的有限元模型。通过模具磨损过程的分析得知，安装模具的磨损集中于中间凸台的侧壁区域，安装模具的最大磨损深度为1.28×10-6 mm，模具寿命的预测值为156250次，模具寿命的试验值为139782次，模拟值与试验值之间的相对误差为10.54%，从而验证了有限元模拟的可靠性。基于有限元模拟结果，分析了工艺参数与模具磨损深度之间的变化关系，研究得知：模具的磨损深度随着铆接速度以及模具深度的增加而增大，而随着模具宽度的增大则呈现逐渐减小的变化趋势。

For the die wear in the self-piercing riveting of 5754 aluminium alloy, the finite element model of installed die wear in the self-piercing riveting of 5754 aluminum alloy with two layers of 2 mm thickness was established by Archard theoretical wear model and software Deform-3D. The analysis of the die wear process shows that the wear of installed die is concentrated on the side wall area of middle convex, the maximum wear depth of installed die is 1.28×10-6 mm, the predicted value of die life is 156250 times, the experimental value of die life is 139782 times, and the relative error between simulation value and experimental value is 10.54%. Therefore, the reliability of the finite element simulation was verified. Furthermore, the relationship between process parameters and die wear depth was studied based on the finite element simulation results. The results show that the maximum die wear depth increases with the increasing of riveting speed and die depth and decreases with the increasing of die width gradually.
