摘　　要：为了研究风雨作用下被动减振装置对输电塔-线体系的控制效果,基于调谐质量阻尼器原理,设计了双向调频减振装置。利用有限元软件SAP 2000建立了输电塔-线体系有限元模型;通过线性滤波法模拟了脉动风速时程;根据降雨形成特征和雨滴谱与强降雨的关系,运用力学平衡和动量定理,得到了雨荷载;根据风雨荷载的组合原则,得到了风雨荷载的时程曲线。运用非线性动力时程分析方法,验证了该双向调频阻尼装置的有效性。In order to research the effectiveness of passive control device for transmission tower-line system vibration control,a two-dimensional adjustable damper was designed based on the principle of tuned mass damper. A finite element model of transmission tower-line was established using software SAP 2000. The linear filtering method was used to simulate the fluctuating wind time history. Rain load was calculated based on the balance of forces and momentum theorem. Wind-rain load time history was obtained according to the combination principle of wind load and rain load. The validity of the damper device was justified by means of nonlinear dynamic time history analysis.
