基于静态参数的旅游轨道线路舒适度设计研究

A Research on the Design of Ride Comfort Degree of Tourist Railway Lines based on Static Parameters

为了在旅游轨道线路技术参数设计时,在保证安全的基础上提升旅游轨道线路舒适度,以陕西省旅游轨道交通线路设计要求为对象,阐述静态平、纵断面参数对线路舒适度的影响,构建基于静态参数的旅游轨道线路舒适度模型,研究曲线半径、外轨超高和曲线长度等静态参数与线路舒适度之间的关系,计算在线路设计速度为60km/h,80km/h和100km/h时,满足不同等级舒适性的曲线半径取值范围,并结合实际地形情况给出满足舒适度需要的曲线半径推荐值,为陕西省旅游轨道设计规范的完善提供理论依据。

To improve the comfort degree of tourist railway line based on ensuring safety in the design of technical parameters, taking the example of the design of tourist railway lines in Shannxi Province, the influence of static horizontal and vertical section parameters on the comfort degree of tourist railway line are expounded, and the comfort degree model of tourist track line based on static parameters is constructed. The relationship between static parameters, such as curve radius, outer rail super-elevation and curve length and line comfort degree, is studied. The range of curve radius satisfying different levels of comfort is calculated as the design speed is 60 km/h, 80 km/h and 100 km/h, and the recommended curve radius meeting the comfort requirement is given by the actual terrain conditions. It provides a theoretical basis for the improvement of the design standard of Shaanxi tourist railway.
