摘要

基于ANSYS软件建立了内侧悬挂拖车转向架构架有限元模型，根据国际铁路联盟标准UIC 515-4制定构架载荷工况进行分析计算，使用Goodman曲线评定其疲劳强度。分析结果表明，构架最大等效主应力为158.19 MPa，最小等效主应力为-97.80 MPa，构架结构的疲劳强度满足要求。

Abstract

The finite element model of trailer bogie frame was built based on ANSYS software. The calculation load and load conditions were developed according to the International Railway Union standards UIC510-5. The fatigue strength of the frame was assessed by using the Goodman curve. The analysis indicated that the maximum equivalent principal stress of fatigue analysis was 158.19 MPa, and the minimum equivalent principal stress was -97.80 MPa, the fatigue strength of the frame structure met the requirement.
