摘 要: 结合动力学方法和能量平衡法,在充分考虑导线结构静力线形、水平张力和导线抗弯刚度共同影响下, 采用数理分析方法研究梯形截面股线缠绕的碳纤维复合芯导线结构的微风振动方程形式。结合碳纤维复合芯 导线与耐张线夹、悬垂线夹连接特点,确定碳纤维复合芯导线边界条件,再将边界条件代入微风振动方程, 求解得到实际碳纤维复合芯导线微风振动方程解的具体形式。研究结果为碳纤维复合芯导线微风振动机理分 析提供了理论依据;另外,对于碳纤维复合芯导线结构微风振动抑制措施的研究也可提供分析依据。
关 键 词: 输配电工程;碳纤维复合芯导线;静力线形;微风振动;数理分析

Abstract: We combined with dynamic method and the method of energy balance, considering the static linear, the conductor structure under the common effect horizontal tension and wire bending stiffness, using mathematical analysis method, researches the actual conductor structure form of the breeze vibration equation. In combination with carbon fiber composite conductor and strain clamp, hanging clamp connection characteristics, the carbon fiber composite conductor boundary conditions were determined. Then the actual carbon fiber composite conductor breeze vibration equations of concrete form were obtained by the boundary conditions substitutting into breeze vibration equation. Research results provide the reliable theory for mechanism of wind vibration analysis and provide analysis basis for the measures research of breeze vibration suppression of aluminum composite carbon fiber core.
