Study on Bogie Frame Reliability of Urban Railway Vehicles

Investigating on the Effects of Random Irregularities of Railway Track by Half-Bogie Model

The vibrations produced by trains include two parts which are deterministic and random vibrations. Due to variation of dynamic loads and patterns of load-time, the random vibration of moving train is one of the most important issues in the field of railway engineering. One of the important sources in producing the train vibrations is rail roughness and irregularities. In this paper, responses o...

Structural Crashworthiness of Railway Vehicles

As a form of transport, rail has always maintained lower accident levels than its counterparts, the car and the airplane. The railway industry, however strives for still better safety measures to be implemented – a fact which intensifies with each accident that occurs. In the last years the continuous developments in technology, computer modeling capabilities and know-how have opened up various...

The Experiment Study for Fatigue Strength of Bogie Frame of Beijing Subway Vehicle Under Overload Situation

In this paper, a problem for safety of bogie frame of subway vehicle under overload situation has been discussed. Firstly, the structure of bogie frame and service condition are introduced to explain the reason caused fatigue failure. Then, the testing points are selected in terms of the structure of bogie frame, the characteristics of processing technique, load transfer path and the operation ...
