摘要

弹性车轮可有效降低轮轨间高频振动和冲击向车体传递，降低轮轨噪声，在有轨电车上得到广泛应用。但在实际运用中，弹性车轮轮箍与轮心之间存在相对旋转运动，并存在迟缓现象，这可能影响车轮寿命和运用经济性，甚者对车辆运行安全性造成影响。文章从弹性车轮橡胶元件性能、车轮抗迟缓扭矩和有无轮轨润滑条件下的车辆振动差异等方面进行分析，比照振动时频图和模态试验得到弹性车轮的固有频率，并得出结论：车辆在轮轨间无润滑状态下通过小半径曲线时，存在共振现象，共振能量较大，这导致轮心、压环与弹性车轮橡胶块接触表面发生转动滑移，从而产生迟缓。为避免共振发生，提出采用合理的轮轨润滑方案，经运用验证，方案有效，弹性车轮迟缓现象消失。

Abstract

Resilient wheels can effectively reduce the transmission of high frequency vibration and impact between wheel and rail

and reduce wheel/rail noise

so they are widely used in tramcars. However

in the process of application

it is found that there is relative rotational motion between the tyre and the wheel center

and the phenomenon of wheel sluggish movement is formed

which may affect the life of the wheel and the economy of operation

or even affect the safety of vehicle operation. In this paper

the performance of the rubber components of the resilient wheel

the anti-sluggish torque of the wheel and the difference of the vehicle vibration with or without wheel-rail lubrication were analyzed

and the vibration time and frequency diagram and the inherent frequency of the resilient wheel obtained by modal test were compared

which concluded that: the wheel sluggish movement of resilient wheels was caused by vehicle resonance when the vehicle passed through the small radius curve without lubrication between the wheel and the rail

the resonance energy caused the contact surface of the wheel center and the pressure ring and the resilient wheel rubber block to rotate and slip. In order to avoid the resonance

reasonable use of wheel-rail lubrication was proposed

and the resilient wheel sluggish movement was proved disappeared after application..
