浅析新建铁路曲线区段接触悬挂的计算条件

Discussion on the Computing Conditions of the Catenary Suspension in the Railway Curved Section

通过比较不同速度条件下的外轨超高对接触网腕臂预配长度、吊弦长度以及接触线拉出值的影响,提出了在新建铁路或增建二线铁路工程中,当线路开通速度小于设计速度时的曲线区段接触悬挂的计算和预留条件。

Through the comparison of the super-high outer rails influence on the pre-assigned length of the contact net bracket,the length of the dropper,and the pulling value of the contact lines under different speeds,this paper puts forward the computing and reserving conditions for the catenary suspension in the curved section when the line s opening speed is less than the designed speed,in the engineering of new railway or second-line railway.
