Due to its inherent low damping, a power transmission line is prone to wind induced vibration. Vibration control is needed to suppress the aeolian vibration of the transmission-line to reduce the fatigue and to extend its service life. Though patented in 1928, more than 90 years ago, the Stockbridge damper or its variants are still commonly used for vibration suppression of conductors in modern day power transmission systems because of their advantages of simple structure, low cost, reliable operation and effective vibration suppression. This paper offers a comprehensive review of the development, modeling, analysis, and design of the Stockbridge-type dampers and their applications in Aeolian vibration control of power transmission lines. A Stock bridge-type damper is a dumbbell-shaped device that consists of a short messenger cable with two masses at the ends and a clamp at the middle to attach to a conductor. The friction among the strands in the messenger cable dissipations energy. A Stock bridge-type damper is essentially a tuned mass damper. For the modeling of a Stockbridge damper alone, the classis linear mechanics analysis, the nonlinear analysis, and finite element method (FEM) are reviewed. For the modeling of the combined damper and conductor system, this paper mainly reviews the Energy Balance Principle (EBP) that is relatively easy to use and can obtain the energy dissipated by the damper. Two important design issues, the damper parameter sensitivity analysis and damper location optimization, are discussed in this paper. This paper also briefly reviews the experimentation and fatigue related to a Stockbridge damper. In addition, this paper provides an outlook of future development, analysis, and application of Stockbridge-type dampers for conductor vibration control.

使用斯托克布里奇型阻尼器的输电线路风沙控制 - 综述

由于其固有的低阻尼,输电线路容易受到风致振动。需要进行振动控制,以抑制输电线路的风振,以减少疲劳并延长其使用寿命。尽管 1928 年获得专利,但 90 多年前,Stockbridge 阻尼器或其变体仍然普遍用于现代电力传输系统中导体的振动抑制,因为它们具有结构简单、成本低、运行可靠和有效抑制振动的优点。本文全面回顾了 Stockbridge 型阻尼器的开发、建模、分析和设计及其在输电线路风尘振动控制中的应用。Stock 桥式阻尼器是一种哑铃形装置,由一根短电缆组成,两端有两个质量块,中间有一个夹子,用于连接导体。吊索中各股之间的摩擦会消耗能量。Stock 桥式阻尼器本质上是一个调谐质量阻尼器。对于 Stockbridge 阻尼器的单独建模,我们回顾了线性力学分析、非线性分析和有限元法 (FEM)。对于组合阻尼器和导体系统的建模,本文主要回顾了能量平衡原理(EBP),它比较容易使用并且可以获得阻尼器耗散的能量。本文讨论了两个重要的设计问题,即阻尼器参数敏感性分析和阻尼器位置优化。本文还简要回顾了与 Stockbridge 阻尼器相关的实验和疲劳。此外,本文对用于导体振动控制的 Stockbridge 型阻尼器的未来发展、分析和应用进行了展望。
