Analysis of Temperature Transition on Disc Brake using the High Speed Brake Dynamometer

초록

The technology of braking performance evaluation has been generally developed along with the improvement of the speed technology of railroad vehicles. Brake system of railway vehicles has a crucial role for the safety as well as riding quality of passengers. And brake dynamometer is designed to simulate the brake characteristic of the high speed train, analyze the experimental object, and also is used to develop and test the brake systems. In this paper, we tried to analyze the temperature transition and/or thermal characteristics of the disc surface during braking using the high-speed camera system with a specially designed lighting system.
