abstract="This article investigates an optimisation strategy for the design of rail-grinding profiles to be used on heavy-haul railway curves, aiming to reduce the rail side wear on curves. A design methodology of rail asymmetric-grinding profiles is put forward based on the principle of low wheel-rail dynamic interaction. The implementing procedure is illustrated in detail. As a case study, the rail asymmetric-grinding profiles were designed for a curve with 600 m radius on Chinese Shuohuang heavy-haul railway. The characteristics of wheel-rail contact geometry and wheel-rail dynamic interaction were analysed and compared between the original standard rail profiles and the designed rail-grinding profiles. The rails on a test curve were ground according to the designed profiles. Before and after rail grinding, both the wheel-rail dynamics indexes and the rail side wear were measured in the field. The theoretical and experimental results show that the wheel-rail dynamic interaction is clearly improved and the rail side wear is alleviated by 30-40% after rail grinding, which validates the effectiveness of the design methodology of rail asymmetric-grinding profiles on curves.<p />",
