摘　　要：阐述了独立旋转车轮踏面设计方法,并根据50kg/m钢轨轮廓设计了新型踏面。轮轨接触几何分析以及动力学计算结果表明,其与LM磨耗型踏面相比,轮轨接触点分布合理,独立旋转车轮动力学性能得到改善。The paper expatiates the way of design the wheel profile for indepenently rotating wheel,and gives new wheel profile based on 50 kg/m rail.Analysis of wheel/rail contact geometry and dynamic simulation show that the contact point between wheel and rail is rational and the dynamic characteristics of independently rotating wheel profile is better than LM wheel profile.

关 键 词：独立旋转车轮 轮轨关系 踏面外形 设计
