[摘要]针对地震作用中输电塔线动力响应分析存在的问题,利用ANSYS有限元软件进行地震波模拟分析。考虑地震行波效应和塔线相互影响,对三塔两线塔线耦联体系进行在典型地震的多点激励下的分析,发现该体系的位移、加速度峰值都比一致激励下的大,且该响应沿着塔高方向越发明显。因此,在进行输电塔线耦联体系抗震设计时,应给予足够重视。

Abstract: In view of the problems existing in the transmission tower-wire dynamic response analysis under seismic action, the seismic wave simulation analysis was carried out by ANSYS finite element software. Considering the influence between seismic traveling wave effect and the tower-wire, three-tower two-wire coupled system suffered multi-point incentive under typical earthquake was analyzed, the results show that the displacement and the peak acceleration value of the system is larger than that suffered the consistent incentive, and the response is more obvious along the tower height direction. So the earthquake resistant design for the transmission tower-wire coupled system should be paid enough attention.
Keywords: tower-wire coupled system; seismic response; traveling wave effect; multi-point incenive
