轮轴扭转振动与曲线地段钢轨波形磨耗

Torsional Vibration of Wheelsets and Curved Rail Corrugations

建立了轮轨垂向－横向－轴扭转空间藕合振动模型，对轮轴扭转振动进行了探讨，认为轴扭转可能激化轮轨系统多种振动，从而诱发钢轨波形磨耗。

A spacial coupling dyna-mic model is formed which involes the vertical,lateral vibration of wheel/ rail system and the torsional vibration of wheelsets. Research is performed on the relationship between the torsional vibration and rail corrugations. It is reckened that the torsion of wheeisets may cause corrugations by exciting manifold sorts of vibrations.
