The supersonic flaw detection technology for the wheel seat inlaid part of the disc braking wheelsets for speed increased passenger cars is described.

And the techniques are applied in the calculation of dynamic stresses and fatigue service life prediction for the outside lever in t he disc braking system of trains.

The problems existing in the braking effort design of disc braking equipment on passenger cars and the harm of them are analyzed.

An entire model of a railway vehicle disc brake system was established.

In the paper, the characterastics of heavy duty disc brake for 160km/h passenger coaches on Canton-Shenzhen were systematically described.

On the basis of the single car rolling test results for the RW25050095 cushioned sleeping car,it is proved that the low friction factor of the disc brake friction pair is the main cause to going beyond the limit in the single car rolling test.

Application and analysis of disk braking technology on locomotive bogie;

In the light of the development of domestic 200 km/h locomotive, it is proposed to develop and grasp second generation of spring bogie-mounted motor technology, featuring AC motor, load type gear case, disk brake and flexible suspension.

Development of a wheel mounted disc brake for a high speed train;

This paper introduces the structural principle of disc brake, probes into the reasons of the failure of disc brake of elevator, and advances some corresponding protective measures.
