城轨交通接触网双导线风载体型系数的选用

Selection of Body-form Co-efficient of Wind for Double Contact Lines of OCS in Urban Mass Transit

对城市轨道交通双导线接触网悬挂风载体型系数进行了计算选用方面的探讨,并对接触线风偏移、计算跨距、支柱挠度和计算荷载的影响进行了分析,建议多导线的风载情况应考虑导线间的屏蔽作用。

The essay discusses the calculation and selection of body-form co-efficient for double contact lines suspension in urban mass transit, analyzes the affection from wind displacement of contact line, calculation of span, curvature of mast and calculating load and recommends that the shield between contact lines shall be considered for wind load of multi-contact lines.
