摘要
Abstract
Based on the tram project in a city,the characteristics and occurrence mechanism of wheel/rail noise of modern trams on typical small-radius curved tracks are analyzed through on-site testing.The wheel-rail relation is im-proved by grinding the rail.The impacts of elastic wheels,rim and rail lubrication on wheel-rail noise control are stud-ied.The results show that when the tram passes through the curved track with small radius,the wheel-rail noise of elas-tic wheels is lower than that of traditional wheels.It is suggested that in the tram system,the wheel flange lubrication should be widely used in small radius curved sections.It is found that through the testing that introducing a rail top fric-tion modifier between wheels and rails to control the friction coefficient within a constant and reasonable range,the creep state between wheels and rails can be greatly decreased and the wheel/rail noise can be effectively reduced there-by.关键词
