摘要
广州地铁5号线采用由直线电机驱动的列车,在运营中出现了较为严重的轨道波磨及车轮圆跳动,造成了车辆走行部的圆跳动发展迅速、电机高度调整装置失效、电机绝缘失效等一系列问题,经过诸如转向架轮轴改造、小曲线段加装轨旁轮轨摩擦控制装置、有针对性的轨道打磨等系统性的整治,轮轨病害初步缓解。
The trains operated in Guangzhou Metro Line 5 are driven by linear motor. During the operation, serious rail corrugation and wheel out of round occurred and equipment installed on bogie and axis are affected. Problems such as the rapid development of circular run - out, linear motor height adjusting device and insulation failure can be relieved with systematic regulation such as bogie axle reformation, friction control device installed at curve trackside and grinding the targeted serious rail. In this way, diseases of wheel and rail initial can be solved to some extent.
