Abstract

The purpose of this research is to put forward a fatigue strength test method for the key parts of the carbody. The body is an important load-bearing part of railway vehicle. The underframe is the basis of carbody structure, is the most main body bearing part. This paper put a more in-depth discussed about how to accurately determine a reasonable constraints and equivalent load when the local component in the test. It could determine more realistic response the carbody underframe’s boundary conditions through contrasting concern regional’s trends in stress and deformation by finite element analysis of vehicle model and the underframe locally model. Based on the minimal total error theory of stress on the region of interest to obtaining for the equivalent load of the vehicle underframe components in the test through contrasting the stresses in the region of interest in the vehicle model and the underframe locally model.
