제동디스크에 따른 마찰계수 특성에 관한 연구

초록

For new brake disc development, the selection of proper friction coefficient and durability in the vehicle design is most important factor to be considered. However, at the present time, not much attention has been given in the study of this field. In this investigation, various types of friction coefficients of railway brake discs, which were newly developed, were examined and characterized. Three different types of brake discs were developed to enhance braking performance, and the braking tests were conducted with a full-scale dynamometer. The braking test was carried out according to Korean railway standards (KRS) guideline. In this paper, the effect of friction coefficients with different types of brake disc was investigated, and the results will be used for the development of new brake disc as well as the related standards
