【摘要】 运用有限元分析软件ANSYS建立了考虑螺栓及法兰作用效果的车轮整体模型。对其进行旋转加载,通过线弹性分析,得到车轮的应力分布。用名义应力法对车轮寿命进行预测,并与试验数据进行对比。结果表明,预测寿命与试验寿命基本吻合,证明了预测方法是有效的。更多还原

【Abstract】 By considering the effect of bolts and flange,the whole model of wheel can be built using ANSYS. According to rolling load and linear elastic analysis,stress distributing can be got. The wheel’s fatigue life can be forecasted by nominal stress. In comparison with the test data,the analysis result is approaching to the test,which proves that this method is effectual.更多还原
