A Study on Analysis of Load Test Result of Bogie Frame for New Electrical Multiple Unit

This paper describes the results of structure analysis and load test of a bogie frame. The purpose of the test is to evaluate the safety and functionality of the bogie frame under maximum load. The bogie system consist of the bogie frame, suspensions, whee/sets, a brake system and a transmission system. Of these components, the bogie frame is the major component subjected to the vehicle and passenger loads. The evaluation method used the JIS E 4207 specifications throughout static load test. The test results have shown the bogie frame to be safe under design load conditions.
