| Abstract: | Based on the current situation of China Railway High-speed,when distance between backs of wheel flanges is 1353,rail base inclination is 1：40,CHN60 is selected as rail,this paper studies the effects of three different wheel treads on relationship between High-speed wheel and rail.The three different wheel treads are LMa used for CRH2,S1002G used for CRH3,and JP-ARC used for the Japanese Shinkanse.The results show that the wheel-rail contact point of LMa and CHN60 is well distributed for maintaining wheel treads,better than S1002G and JP-ARC＇s wheel-rail contact point distribution.Meanwhile,the paper explores the effects of these three different wheel treads on stability of the vehicle by comparing its wear and derailment quotient.The conclusion is that stability of the vehicle decreases in each kind of wheel tread as the vehicle speed increases.S1002G is superior to JP-ARC and LMa in stability.LMa is superior to JP-ARC and S1002G in wear.And S1002G is superior to LMa and JP-ARC in safety（derailment quotient）. |
| Keywords: | relationship between wheel and rail stability wear derailment quotient |
