基于平稳性的旅游轨道线路平面参数研究

Analysis and Research on the Plane Parameters of Tourism Rail Transit Lines Based on Stationarity

从Sperling模型对铁路线路运行平稳性评价方法的设计理念出发,以陕西省旅游轨道线路设计要求为对象,考虑在陕西省范围内建设旅游轨道线路时,平面参数设计对列车平稳性的影响,通过建立平面曲线半径、运行速度和振动频率3个变量与列车运行平稳性之间的函数关系,分析计算了在线路设计速度80 km/h和100 km/h条件下旅游轨道交通平面设计参数的平稳性指标值,提出了符合运行平稳性标准要求的曲线半径推荐值,为陕西省旅游轨道平面线路设计规范提供依据。

In this paper, the Sperling model is used to design the evaluation method of railway line running stability. The influence of the plane parameters on the train stability in the construction of the tourist track in Shaanxi Province is studied based on the requirements of the design of Shaanxi tourist track line. The relationship between the three variables of the plane curve radius, the running speed, and the vibration frequency and running stability of the train is established. This paper analyzes and calculates the smoothness index value of the plane parameters of the rail transit under different speeds of 80 km/h and 100 km/h, respectively. The recommended value of curve radius is put forward, which can meet the requirements of the standard of running stability, to provide the basis for the design of the track plane circuit in Shaanxi province.
