摘要: 针对覆冰输电导线舞动问题,建立单导线与六分裂线路有限元模型,分析单导线与六分裂线路的舞动响应特性,提出一种基于垂吊式调谐质量阻尼器(tuned mass damper,TMD)控制方案来抑制舞动。基于ANSYS有限元平台,分别建立单导线与六分裂导线的精细化有限元模型,模拟分析其舞动全过程,并依据模态分析结果与TMD参数优化理论设计阻尼器关键参数。对垂吊TMD在线路中点、四分点的单点、两点及三点的布置策略及质量比的影响进行研究,发现三点布置方案能最有效地抑制整体线路的舞动,当质量比为2%时可实现舞动的基本抑制,垂吊TMD方案止舞效果显著。

Abstract: To address the issue of iced conductors galloping, finite element models of both single and six-bundle conductor lines are established to analyze their galloping response characteristics. To suppress galloping, a control strategy based on a suspended tuned mass damper(TMD) is proposed. Based on the ANSYS finite element platform, refined finite element models of a single conductor and a six-bundle conductor are established respectively to simulate and analyze the entire galloping process. Key damper parameters are designed in accordance with modal analysis results and the theory of TMD parameter optimization. By studying the influence of TMD placement strategies-single-point, two-point, and three-point arrangements at the mid-span and quarter-points-as well as the mass ratio, it is found that the three-point configuration most effectively suppresses galloping across the entire line. When the mass ratio is 2%, basic galloping suppression can be achieved, and the suspension TMD scheme has a significant effect on galloping suppression performance.
