Abstract
The wheel fatigue life of truck is the main indicators to determine its performance.In order to better analysis and forecast the fatigue performance of wheel.Proposed a set of complete the finite element analysis method of the wheel's fatigue durability based on the national standards of the dynamics bending and radial fatigue testing for vehicle wheel.Through established the finite element model of the wheel and the method used discrete curve as the cyclic loads in order to simulate the actual boundary condition of wheel structure more correctly.And then,the simulation result obtained its stress distribution and critical areas.By using software of fatigue analysis,the fatigue life of the wheel is calculated and analyzed.Afterwards,the dynamic bending and radial fatigue test are conducted and the test results are compared with the simulation results.Based on the contrast,the validity of the method is verified.This method can predict the critical areas and durability of the wheel structure under radian and bending loads accurately.Also it provide a guidance to evaluate its performance and lay a foundation for further design of wheel structure.关键词
