Abstract:
Based on the finite element analysis software ABAQUS,the rotary fatigue life of the aluminum alloy wheel is simulated.The initiation point of the fatigue crack and its maximum stress are obtained.With the nominal stress method,the S-N curve of the aluminum alloy wheel is established,and the stress amplitude and mean stress are calculated.After inputting equivalent stress amplitude to the S-N curve,the fatigue life of the aluminum wheel is predicted.The benches of the prototype wheel and the improved wheel are tested and the simulation results are verified.The results show that the nominal stress method may be a better method to predict the fatigue life of aluminum alloy wheels.
