大坡度条件下接触网机械计算研究

Researches of Mechanical Calculation of Overhead Contact Line under Conditions of Steep Gradient

对大坡度条件下接触网机械计算的相关理论进行研究,对比分析了在不同坡度条件下采用抛物线法、悬链线法以及弦线法计算的悬索形状特征值,弦线法相比于抛物线法考虑了坡度因素,更适用于大坡度条件下的接触网悬索形状计算。

The paper analyzes related theories for mechanical calculation of overhead contact line under conditions of steep gradient,compares and analyzes the characteristics value of suspension cables by adopting of parabolic method,catenary method and chord-line method,among which,chord-line method,with considering the factors of gradient,is better than parabolic method and is more adaptive for calculation of suspension cables of overhead contact line under conditions of steep gradient.
