云巴线路平面曲线参数研究

Research on plane curve parameters of Sky Shuttle line

结合云巴车辆的构造及云巴系统的性能要求,对其舒适度标准及平面曲线参数进行分析研究,得出以下结论及建议:①云巴的舒适度指标与TB 10098-2017《铁路线路设计规范》采用相同的指标,以便于系统制式的推广;②折返线、停车线、出入线等辅助线的最小曲线半径宜与道岔导曲线半径保持一致,取20 m;在一般情况下正线的最小曲线半径不宜小于100 m,困难条件下不宜小于30 m;车站范围内的曲线半径设置应考虑屏蔽门安装的要求,最小曲线半径不宜小于300 m;③在云巴的设计中,在缓和曲线长度受限的条件下,建议适当降低实设超高以提高线路上限通过速度。

In view of the structure of Sky Shuttle vehicle and the performance requirements of Sky Shuttle system,this paper analyzes and studies the riding comfort standard and plane curve parameters,making the following conclusions and suggestions:①the riding comfort index of Sky Shuttle is the same as that of TB 10098-2017 Code For Design Of Railway Tracks,so as to promote the system standard.②The minimum curve radius of siding tracks such as turnaround track,parking track and arrival/departure track should be consistent with that of turnout guide curve,which is 20 m.In general,the minimum curve radius of the main track should not be less than 100 m,and it should not be less than 30 m under difficult conditions,The setting of curve radius within the station should consider the installation requirements of platform screen gate,and the minimum curve radius should not be less than 300 m.③In the design of Sky Shuttle line,under the condition of limited length of transitional curve,it is suggested to reduce the actual superelevation appropriately to improve the maximum speed of the line.
