Validation of A356T6 automobile wheel fatigue strength using the finite elements method

Abstract

In this study, A356T6 wheel bending fatigue test limits determined using the finite element methods and compared to experimental test results. In experimental test, zinc-glycerin was applied front surfaces of wheels to obtain fatigue detects. Short and long cycle bending fatigue tests (200.000 and 1.800.000 respectively) were performed. Simulation model was created in Ansys by defining A356 S-N curve. Simulation performed has been with test parameters. According to simulation results, the crack starts 225.000 cycle in short-test and 2.000.000 cycle in long -test. According to the results, it has been revealed that the experimental and analysis data are parallel to each other.
