接触网振动分析及防振措施

本文从理论上推导了接触网振动的公式和频率,分析了影响接触网振动的因素。根据实际情况计算了接触网在不同频率下振动的振幅,并相应提出了可采取:1)在线路两侧和高路堤区段种树;2)在跨距中间加类似于失谐摆等防振设备;3)合理设置锚段内的跨距等防振措施。

Analysis on Vibration of OCS and its Vibration Proofing Provisions

The article deduces theoretically the formula and frequency for vibration of OCS, analyzes the factors influencing the vibration of OCS, calculates the different vibration amplitude under various frequencies and raises the following provisions: 1) planting trees on higher embankment and at both sides of railway; 2) adding equipment similar to detuning equipment for vibration proofing at middle of the span; 3) setting adequately the span spacing in overlapping section.
