摘要：

为了研究铝合金锐棱成形模具的磨损规律，以采用锐棱造型设计的某车型铝合金翼子板为研究对象，利用CATIA软件构建了翼子板拉延成形模具的三维几何模型，并借助Autoform有限元仿真平台对翼子板拉延成形过程进行了数值模拟。基于数值模拟结果和Archard磨损模型应用Python进行二次开发，建立了可在Autoform有限元仿真平台进行模具磨损分析的模拟方法和流程，从而快速获得翼子板锐棱成形模具的磨损仿真结果。根据磨损仿真结果，对翼子板锐棱成形模具进行了针对性的表面强化处理，提高了翼子板锐棱成形模具的耐磨性，通过大批量生产验证，翼子板锐棱成形模具无过度磨损，可以满足连续应用的需求。研究表明，将Python二次开发应用于Autoform有限元仿真平台，能够高效、准确地得出锐棱成形模具的磨损规律。

In order to study the wear laws of the sharp edge forming die for aluminum alloy, for the aluminum alloy fender of a certain vehicle model with sharp edge design, the three-dimensional geometry model of drawing die for fender was constructed by using software CATIA, and the drawing process of fender was numerically simulated by the finite element simulation platform Autoform. Then, based on the numerical simulation results and Archard wear model, the secondary development was conducted by Python, and a simulation method and process for die wear analysis were established on the finite element simulation platform Autoform to quickly obtain the wear simulation results for the forming die of fender with sharp edge. Furthermore, according to the wear simulation results, the targeted surface strengthening treatment for the forming die of fender with sharp edge improves the wear resistance of the forming die for fender with sharp edge, and through mass production verification, the forming die of fender with sharp edge has no excessive wear, which could meet the continuous production requirements. The results show that applying the secondary development of Python to the finite element simulation platform Autoform can efficiently and accurately obtain the wear laws of the sharp edge forming die.
