槽型轨磨耗演变过程数值模拟
Nu merical simulation of groove track wear evolution
摘要
Abstract
This paper adopted the multi-body dynamics analysis software UM to study the wear law of rail.Tak-ing the self-developed 70%low-floor trams as an example,the rail wear calculation model of 59R2 groove was establisked on the basis of the wheel-rail multi-point contact theory.The groove track wear situations at ease curve,circular curve and line area were analyzed.The results show:Wear is focused on rail shoulder at outside track of circular curve.When the trams passed less frequently,the wear is focused on rail head and shoulder at inner track.With the increasing numbers of the trams,the wear of the groove is equaled to that in the rail head and rail shoulder.The amount of wear at ease curve track is much less than that on the circular curve.Outside track’s wear is focused on rail shoulder while inner track’s wear is focused on both rail head and rail shoulder. In straight line,the amount of wear on left and right side is similar and far beyond the wear on ease curve and circular curve.关键词
