Virtual Impact Test for Aluminum-Alloy Wheel Based on Numerical Simulation Method

Abstract:

The mechanical properties of car wheel mast have high reliability requirements. The impact test for trial casting aluminum alloy wheel must be passed, which is one of the bench tests. Based the practical case, the integrated finite-element model for virtual test is established, including impact block, wheel, tire, bracket, rubber pad, the standard test load conditions are imposed, and the entire impact process was simulated by finite-element method, the velocity, displacement and kinetic energy curves of the impact block, the stress distribution and the impact force curve of change were obtained. Moreover, using in a typical case, compared with the physical impact test, the model and procedure of the finite-element numerical simulation was verified. The modeling method and calculation procedure given can guide the virtual design of aluminum-alloy wheel, the blindness of design can be reduced, and the development work efficiency can be increased.
