With the simulated result and theline test,some of factors which affect the wheel/rail force are discussed,andsOn1e of relationships between the shapes Of scuffing wheeltread and thewheel/rail force are established.

应用车辆－轨道耦合动力学原理，对由踏面擦伤引起的轮轨间非稳态垂向动力效应进行计算机模拟分析；并结合试验讨论了影响轮轨接触力的诸因素，建立了轮轨接触力与踏面擦伤形状之间的关系；对踏面擦伤的线检测仪器的开发提供了理论依据。
