中低速磁浮交通线路最小坡段长度研究

On Minimum Length of Gradient Section for Medium and Low Speed Maglev Train

借鉴轮轨系统城市轨道交通交通线路最小坡段长度的确定方法,结合中低速磁浮车辆的技术特点,分析得出中低速磁浮交通线路的最小坡段长度主要与列车的行车平稳性和乘客的乘坐舒适度有关。综合考虑由竖曲线切线长度和夹坡段直线长度所确定的最小坡段长度以及由列车长度所确定的最小坡段长度,计算推导出中低速磁浮交通线路的最小坡段长度一般情况为180m,困难情况为140m。

By learning how to determine the minimum length of gradient section of wheel-rail urban rail transit,and combined with technical traits of the medium and low speed maglev train,the relationship between the train running stability and the comfort level of passengers is analyzed,which will determine the minimum length of gradient section for the maglev train.Meanwhile,since the minimum length of gradient section is jointly determined by the vertical curve tangent length,the length of straight line between two gradients,and the train length.Finally,it is concluded that the minimum length of gradient section for maglev line should be 180 m in general condition and 140 m in difficult condition respectively.
