A Study on the Temperature Measurement at the Disk Brake of a High-Speed Rail Transit by the Non-Contact Method

비접촉 방법에 의한 고속철도 디스크 브레이크에서의 온도측정에 관한 연구

As the speed of rail transit is higher, it is very important to secure the safety and confidence of the braking device and in the point of view, by means of the rise of the temperature from the friction between the disk and pad which are the actual part of a braking system, the damage of brake disk is the main cause to lose the safety of braking device. Therefore, in this study, to predict the danger of a disk brake and to know its max. temperature in the train service the module of a temperature measurement by the non-contact method was developed.
