摘要

利用Fluent流体动力学软件模拟双分裂导线绕流场，计算两根子导线的空气动力系数，得到背风侧子导线的升力系数和阻力系数随其与迎风侧子导线相对位置的变化规律。进而利用ABAQUS软件模拟典型双分裂线路段的尾流诱发振荡过程，获得两根子导线的运动轨迹、振动幅值和频率特征。结果表明，两子导线的位移相位相反，运动轨迹近似为水平椭圆，与现场观测一致。模拟分析了间隔棒等间距和非等间距排布方式下双分裂导线尾流诱发振荡的特征。

Abstract

Lift coefficient and drag coefficient of leeward conductors varying with relative position of upwind conductors were simulated by fluid dynamics software Fluent. The wake-induced oscillation of typical twin bundle conductor lines were numerically simulated by ABAQUS software. The moving traces,vibration amplitude and frequency characteristics of sub-conductors were obtained. It is shown that the displacement phases of the two sub-conductors are opposite,and the moving traces are approximated as a horizontal ellipse. The simulation results are consistent with the field observation results. Finally,the characteristics of wake-induced oscillation of the twin bundle conductor line with equally and unequally installed spacers are compared.
