摘要：

In order to predict the service life of automotive cover dies, the Archard wear model was optimized to establish a dynamic wear model. The model coupled the dynamic wear coefficient and the surface hardness change curve. This model converted the wear coefficient K into a dynamic wear coefficient that varied with contact pressure and relative slip velocity, the surface hardness was converted into a dynamic hardness curve that varied with the depth of wear. Then, the Python language was used to develop the ABAQUS software for a second time, and the dynamic wear model was coupled to the finite element simulation, and the wear calculation of the die of automotive covering parts considering the wear coefficient and the depth change of the hardened layer was realized. By comparing and analyzing the dynamic wear evolution law of the typical positions of the convex and concave die during the forming processes, and taking the maximum wear depth of the die as the failure criterion, the service life of the stamping die of the aluminum alloy cover is 635 428 times. The main wear of the die was concentrated near the die clamping line and at the large rounded corner, and these positions need to be repaired and debugged in actual production, which may extend the service life of the die effectively. © 2024 Chinese Mechanical Engineering Society.
