很早以前人们就知道锥形车轮要产生横向振动问题。随着列车速度的提高和重量的增加,横向振动的危害愈加严重了。在一定的速度下可能产生持续的横向振动,即蛇行运动。无论线路多么直,轮对的横向振动都是不可避免的,它导致两侧轮缘交替地贴靠钢轨,而每当轮缘冲击钢轨时,都要招致力的作用,这些力可能造成车辆和线路的损坏,而且还会使旅客感到不舒适,在最不利的情况下,还有脱轨的危险。蛇行运动妨碍安全可靠和经济有效的高 Long ago people knew that the conical wheels had to generate lateral vibrations. As the train speed increases and the weight increases, the damage of transverse vibration becomes more and more serious. At a certain speed may produce sustained lateral vibration, that is, the serpentine movement. No matter how straight the line is, the lateral vibrations of the wheelset are inevitable, which causes the rims of both sides to abut against the rail alternately, and each time the rim impacts the rail, force is exerted which may cause the vehicle and / The damage to the route, but also to the traveler’s discomfort, is also at risk in the worst case of derailment. Winding movement hinder safe and reliable and cost-effective high
