摘要
列车乘坐舒适度是城市轨道交通设计过程应首先考虑到的因素。其中,线路最小坡段长度的选取对于其有着重要影响。而对于云巴系统来说,目前相关规范未对线路最小坡段长度做出明确的规定。参考跨坐式单轨等城市轨道交通制式线路最小坡段长度的计算方法,结合云巴系统自身的技术特点,通过动力学软件仿真分析与计算,得出云巴系统线路的最小坡段长度的取值。综合考虑影响最小坡段长的多种因素,包括远期列车长度、竖曲线半径及切线长度等,可以得出云巴系统的最小坡段长度一般情况下可以取200 m,困难情况下可以取100 m。
Train ride comfort is the first factor to be considered in urban rail transit design process.Among them,the selection of the minimum slope length of the line has an important influence on it.For the Yunba system,the minimum slope length of the line is not clearly stipulated in the current relevant standards.This paper refers to the calculation method of the minimum slope length of urban rail transit system lines such as straddle monorail,combined with the technical characteristics of Yunba system,through dynamic software simulation analysis and calculation,the value of the minimum slope length of Yunba system lines.Considering various factors affecting the minimum slope length,including long-term train length,vertical curve radius and tangent length,it can be concluded that the minimum slope length of Yunba system can be taken as 200 m in general and 100 m in difficult cases.
