Vibration Analysis of Tread Brake Block in the Brake Dynamometer for the High Speed Train

초록

This paper deals with the frequency analysis of the abnormal vibration in the specific speed range when the tread brake test is applied in the brake dynamometer. Generally brake system of railway vehicles has a crucial role for the safety as well as riding quality of passengers. And dynamometer tests are widely used to evaluate the friction and wear performance of railroad friction composition brake shoes including the emergence brake, continuous brake, and so on. Experiments on the brake dynamometer for the high speed train are provided to illustrate the frequency analysis of the abnormal vibration in vehicle speed at 140 [km/h] and 70 [km/h] under the 920 [mm] wheel diameter using the 3-axis accelerometers.
