摘要
采用被动摩擦阻尼器研究了输电塔在强烈地震作用下的减震控制问题。采用多自由度模型建立了输电导线的动力分析模型。针对输电塔线体系的平面内振动和平面外振动分别建立了安装有被动摩擦阻尼器的塔线耦联体系的动力分析模型和动力分析方法。结果表明,摩擦阻尼器是一种形式简单、具有较好耗能能力的控制装置,可以有效地减小高压输电塔的地震反应。
The vibration mitigation of transmission tower subjected to seismic excitations is actively carried out in this research. The multi-degree-of-freedom （MDOF） mode/of transmission line is also constructed. The dynamic model and analytical method of transmission tower-line system incorporated with passive friction dampers are developed for both in-plane/out-of-plane vibrations. The analytical results indicate that the passive friction damper has simple configuration as well as satisfactory energydissipating capacity and thus can be utilized to effectively suppress the seismic responses of transmission tower-line system.
