| 摘 要： | 利用SolidWorks和Ansys软件建立22.5 in×9.0 in无内胎钢制车轮的有限元分析模型,采用高强钢代换低强钢的方法,在保证强度和疲劳寿命的前提下,对车轮进行了轻量化设计,减薄了轮辋和轮辐厚度。弯曲和径向试验的仿真结果表明:虽然改进后的各自最大等效应力都有所增加,但都没有超过材料的屈服极限;采用名义应力法并根据经验公式建立的590CL材料的S-N曲线方程,计算得出的疲劳寿命符合GB/T 5909—2005标准要求。

| Abstract: | The finite element analysis model of 22. 5 in×9. 0 in tubeless steel wheel is established by using SolidWorks and ANSYS software. The method of replacing low strength steel with high strength steel is adopted. On the premise of ensuring the strength and fatigue life, the wheel is designed with light weight to reduce the thickness of rim and spoke. The simulation results of bending and radial tests show that although the maximum equivalent stress of each improved material is increased, the yield limit of the material is not exceeded. By using the nominal stress method and the S-N curve equation of 590CL material established according to the empirical formula, the calculated result of the fatigue life meets the requirements of GB/T 5909-2005 standard. |
