Radial Fatigue Analysis of Steel Hub Based on Finite Element Analysis

The fatigue strength of the steel hub is important to the safety of the automotive wheel and the dynamic radial fatigue test is also one of the three performance experiments for evaluating the safety of automotive wheel. This paper applied Abaqus in analyzing the static strength of the 13×4.5B automotive steel hub according to the test requirement of national standard, and to calculate the hubs fatigue life by Fatigue. Compare the FEA result and the test result, find the two results are very closer which proved the correctness of the static strength analysis and the fatigue strength analysis, and the FEA simulation can efficiently predict the fatigue life of automotive wheel and it does a good for the wheel design to reduce the design cost and to shorten the development cycle.
