Evaluation of Fatigue Strength of the Bogie Frame for Electrical Multiple Unit

초록

The bogie frame, which is a running system for railway rolling stock, is a key structural part that supports the car body’s load, and significantly influences the safety of the passengers and the railway vehicle, running performance, and riding comfort. The bogie frame, which designates the structure of the bogie, has a complex configuration, directly supports the loads. It involves complex application of both static and dynamic loads, and is subject to the static load due to the car body’s empty weight and passenger weight, and the motion mode of the car body, running system, and wheel axle. The structural analysis was conducted for the test loads of the vertical load, twist load etc. and The performance test was conducted
