A Study on the Structural Fracture of Body Structure in Railroad Car

초록

An evaluation was carried out by applying a load to the underframe of the freight car to determine the structural strength of the carbody of a newly manufactured freight car for transportation. This study is aimed at evaluating the safety of the underframe of the freight car. Loading test were performed under the loading condition. Prior to the evaluation of structural strength, finite element method software was used for structural analyses on stress distribution in a carbody of a freight car. The strain gauges were attached on the carbody based on FEM results. A vertical load test, compressive load test, measurement of deflection amount and a natural frequency measurement test were conducted.
