The nationalization of the braking system for urban rail cars is researched.

In this paper, the principle of model selection for urban rail cars are put forward.

In order to measure the performance of urban track vehicle bogie rapidly and accurately, the measurement platform for urban track vehicle bogie is set up based on virtual instrument programming language of LabVIEW and testing technique of PXI bus.

As urban track vehicles develop dramatically, there is an increasing demand in the performances of their bogies.

The automatic door is an important part for urban rail vehicles,characterized by belt and screw motions.

An experiment system for traction simulation of urban rail vehicles is put forward,and the simulation of traction and electrical braking working conditions under different loads of rail vehicles can be realized;On the basis of the technical platform with virtual instruments,the real-time collection and analysis of the feature parameters of traction motors are carried out.

,for testing urban rail vehicle is described.

Stimulant traction system of the urban railway vehicle with 30kW AC motor;

This paper introduces the test and speed regulating control for the traction experimental system of urban railway vehicle.

Control method of resistance braking energy was proposed according to the continual start-up and braking of the urban railway vehicle,and the resistance braking energy was made reasonable use of and the energy consumption was reduced in the on-board resistance.
