Abstract

characteristic of wear between wheel and rail is important factor of judgement to maintenance. KHST is optimized on an exclusive rail, UIC60. but also KHST is running on the variety existing line as well as KS50N, KS60 et,c. Hail profile of KS50N is dissimilar to DIC60. So we can predict that characteristic of wear is embodied also different. In this paper. we deduced the force and point of contact position between wheel and rail through multi-dynamics analysis and predicted wear of wheel and rail through contact problem analysis. we used simplified theory of kallker on contact problem, and Predicted the wear phenomenon of wheel using archard wear equation about each condition.
