摘要
高速行车条件下,轮轨间的冲击振动显著增强,成为不容忽视的问题。本文应用车辆-轨道耦合动力学理论,并借助于所编制的轮轨相互作用仿真软件VICT分析系统,详细研究了钢轨焊接接头、波浪形磨耗钢轨、擦伤车轮、偏心轮以及不圆顺车轮等常见轮轨激扰所导致的轮轨冲击振动在高速行车条件下的形态特征,给出了各类冲击振动随列车运行速度的变化规律,在此基础上提出了控制高速铁路轮轨冲击振动的一般原则。
Wheel/rail impact vibration will increase dramatically in high-speed railway operation.In this paper,based on the theory of vehicle-track coupling dynamics and the associatedcomputer software VICT,the modes and characteristics of wheel/rail impact vibrations dueto welded rail joints,corrugated rails,flat wheels,eccentric wheels and non-circular wheelsare investigated in high-speed railway operation.The variations of impact vibrations with thetrain running speeds are given out.And the general principles are suggested to control wheel/rail impact vibrations in high-speed railway operation.
