Analysis of Impact Test of Aluminum Disc Wheels Based on FEM

Aluminum disc wheels have to pass impact test before going into production. Impact test of “15×6J” wheel is analyzed with CAE technology, representing the application of finite element method on simulation of impact problems. In numerical simulation of wheel impact test, integrated finite element model is established, including impact block, wheel, tyre and bracket. The whole process of impact is simulated, and velocity and displacement curves of impact block and wheel stress distribution are obtained. The analysis results indicate the wheel can pass the impact test, which is validated by the physical experimentation.
