In order to predict the radial fatigue life of full surface steel wheel, a finite element analysis model for full surface wheel under radial fatigue test condition is established, with consideration of the effects of test pressure of tire on wheel, and making the radial load applying process as close as possible to real conditions. Apply-ing changing radial load to find the location of dangerous area, get the loading history of the hazardous node of wheel, and hence predict the fatigue life of wheel in radial fatigue test. ANSYS Workbench platform is used for the first time in China to conduct the radial fatigue analysis of wheels, providing a quick and reliable method of wheel radial fatigue analysis.%为对钢制全表面车轮的径向疲劳寿命进行预测,本文中针对全表面车轮的径向疲劳试验工况建立了有限元分析模型,考虑了轮胎的试验气压对车轮的影响,且使试验中径向载荷的施加过程尽可能接近真实工况.加载变化的径向载荷后得到危险区域的位置并得到车轮危险节点的载荷历程,预测车轮在径向疲劳试验时的疲劳寿命.在国内率先使用ANSYS Workbench分析平台对车轮进行径向疲劳分析,为车轮的径向疲劳分析提供了一种快捷且可靠的分析方法.
