Research on Key Technologies of Intelligent Repair of Running Gear of Urban Rail Vehicles

This paper describes the structural analysis, load tests and combined stress of the bogie frame. It seeks to identify the structural safety of the bogie frame when the bogie is assembled on the train and a train service is implemented. The bogie consists of the bogie frame, suspension, wheels, brakes and transmission, etc. The bogie frame can be considered as the most important part of the bogie. The analysis and tests were evaluated using JIS E 4207 standards and performance test standards for urban rail vehicles.

Hybrid Electric

In order to improve the efficiency and environment-friendliness of urban rail vehicles, a new hybrid electric locomotive is proposed. The general structure of the proposed hybrid electric locomotive is given and analyzed from a dynamics point of view. The calculation method of power output and its allocation strategy is discussed. A simulation is conducted in HELSP(Hybrid Electric Locomotive Simulation Platform) to verify the performance of the power allocation strategy. The result indicates that the function of allocating power can be properly realized, and the regeneration energy from frequent braking can be absorbed by the power storage of the vehicle.
