Development of the Braking Performance Evaluation Technology for High-speed Brake Dynamometer

초록

Brake system of railway vehicles has a crucial role for the safety as well as riding quality of passengers. And the technology of braking performance evaluation has been generally developed with technology of speed improvement of railroad vehicle. Brake dynamometer is designed to simulate the brake characteristic of the high speed train, and has a function of record the data which can be reproduced and help to analyze and compare the experimental object, and also is used to develop and test the brake systems. In this paper, we tried to test braking friction materials (disc brake and block brake) for the high speed rotation which is in a current use commercially, and its results will be introduced by means of arranging of a braking performance test evaluation technology on braking friction materials of railway vehicle using the high speed dynamometer (400 [km/h]-grade).
