Research on Train Bogie Frame Service Performance Characterization Parameters Based on Dynamic Loads

Abstract

The bogie frame, an important component of an urban rail train, plays a vital role in the safe operation of the trains. In this paper, a three-dimensional finite element numerical simulation analysis model is constructed. The mechanical deformation trend and modal parameters of the frame under different operating conditions are analyzed to obtain deformation and modal characteristics of the frame. Furthermore, the extraction and calculation methods of the service performance characterization parameters of the frame under different operating conditions are proposed based on the numerical simulation.
