Finite element analysis and evaluation of bogie frame for Passenger locomotive based on reliability

Abstract

Passenger locomotives are developing rapidly in the direction of high speed, high power, energy saving, environmental protection, and light weight. In order to avoid locomotive failures such as fatigue fracture, the requirements for reliability and fatigue strength are becoming increasingly higher. The passenger locomotive running steadily and safely mainly depends on whether the design of the steering frame structure is reasonable. Based on the locomotive bogie by 3D solid modeling, the static strength and modal analysis of ANSYS finite element analysis software is applied to the reliability of the operation stage to make judgments and a reliability evaluation model frame is set up based on finite element analysis.
