旋转止挡结构间隙对100%低地板有轨电车动力学性能的影响

Impact of Rotation Stopping Block Structural Gap on 100% Low-floor Tram Dynamic Performance

为了研究二系旋转止挡结构间隙对100%低地板有轨电车动力学性能的影响,根据轮轨系统设计的相关要求和100%低地板有轨电车的基本参数,利用SIMPACK动力学分析软件建立了浮车体有轨电车的动力学模型。针对有轨电车在实际运行中存在的一次车体蛇行问题,利用实车模型,重点分析了二系旋转止挡间隙值选取,并阐述了有无间隙对直线上车体稳定性的影响。结果表明,二系旋转止挡间设置2.0mm的间隙,可以明显改善车体一次蛇行状况。

To study the influence of the binary system rotation stopping block gap on the dynamics performance of 100%low-floor tram,according to the relevant requirements of wheel/rail system design and the basic parameters of 100%low-floor tram,dynamics analysis software SIMPACK is used to establish the pontoon-type vehicle model.Based on the actual vehicle model,and focusing on the primary hunting problem existing in tram operation,the selection of secondary rotation stopping block clearance value is mainly analyzed,the influence of rotation stopping block clearance on vehicle stability while running on straight line is elaborated.The results show that the secondary rotation stopping block clearance within 2.0 mm will obviously improve the dynamic performance of low-floor tram in terms of primary hunting.
