摘要
风荷载是接触网设计中主要的可变荷载,风速取值的正确与否对接触网的运行安全及系统的经济性至关重要。本文指出了常规设计中在风速取值及风荷载计算方面存在的问题,通过借鉴其他行业及国外做法,结合本行业特点,提出与风速相关的各参数的取值建议。
Wind load is a main variable in OCS design, its right selection is very important for safety operation of OCS and economic efficiency of the system. The paper points out the problems existed in selection of parameters relative to wind speed and wind load calculation in conventional design, presents proposals on their selection by referencing methods used by other professions home and abroad and by considering the characteristics itself.
