| Abstract: | In this paper,600 MPa grade martensitic phase steel with excellent forming properties is selected to make complex spokes and 540 MPa grade bainite duplex steel to make rims.The three-dimensional model and finite element model are established.The static analysis and dynamic analysis are used to simulate the wheel bending and radial conditions respectively,and the stress concentration points and their maximum stress and strain values which are prone to fatigue cracks are obtained.The E-N curve of the high-strength steel wheel is established by the fatigue life nominal strain method,and the fatigue life analysis of the wheel is performed by the fatigue analysis software.The simulation results show that the position of the maximum stress in the 2 test simulations is consistent with the position of the test,which verifies the effectiveness of the finite element method for estimating wheel life. |
