摘　　要：在单轨交通线路系统中,由于单轨系统特点,对轨道线路的要求指标比地铁系统相对较低。因而展线更加灵活,所采用的超高较大、缓和曲线较短、曲线半径可以更小。基于这些特点,车辆在曲线超高路段运行时,线路超高变化对列车的影响也更加突出。降低超高变化率可以控制颠簸强度从而提高行车的平稳性。Because of the characteristics of the monorail lane system, the requirement of track circuit indicators is relatively lower in monorail system than that in the subway system. Therefore, designing the lines is more flexible. The adoption of the ultra-high can be greater, the curve can be shorter and the curve radius can be smaller. Based on these features, when vehicles are running at the ultra-high curve sections, the effect of ultra-high change of the lane on the vehicles also becomes more prominent. The intensity of turbulence can be controlled in order to improve the smoothness of driving by decreasing the ultra-high changing rate.
