摘要

基于Ansys有限元软件，分析国内某地铁用弹性车轮压装过程和服役过程的应力，对服役过程的疲劳进行评估，并对实物进行疲劳试验，分析疲劳试验前后刚度变化。结果发现：弹性车轮压装过程中，压盖为等效应力最大的组件，周向拉应力占主要贡献；弹性车轮服役过程中，压盖螺栓孔等效应力是其他组件的1.5倍以上，其中周向应力占主导作用；轮箍疲劳薄弱部位为轮箍内侧与橡胶接触区域，压盖疲劳薄弱区域为螺栓孔区域：弹性车轮经过疲劳试验后，金属元件探伤未发现疲劳裂纹，刚度变化小于20%。

Abstract

The stresses was analysis in press-fitting and in service, and fatigue was evaluated based on ANSYS software in this thesis. What’s more, the fatigue test was carry out, stiffness variation was analyzed before and after fatigue test. The result show that, the pressure ring is the largest Von-Mises stress component in press-fit, and the hoop tensile stress pay a important role. The Von-Mises stress on hole of pressure ring is 1.5 times than other component in service, and the hoop stress pay a important role. The weak anti-fatigue area of tyre is on back side of tyre, and The weak anti-fatigue area of pressure ring is on hole. No fatigue crack was found, and the stiffness variation was less than 20% after fatigue test.
