STUDY ON THE ESTIMATION OF ADHESION FORCE FOR DISC BRAKE IN SKID CONTROL CONDITION

초록

The braking performance has become more important due to the increase of the train speed. The brake system of train must possess the large braking effort in order to stop the train safely within the limited stopping distance. But, the excessive braking effort has been deteriorated the ride comfort and sometimes occurred the skid. Therefore, it is necessary to control appropriately the braking effort within the adhesion limit. The present paper has suggested an analytical method to review the relation between braking and adhesion forces for the disc brake. The analysis has been applied to the actual disc braking control for the disc brake of Korea High Speed Train (HSR350x) and the adhesion forces have estimated in the real skid condition.
