摘　　要：采用ABAQUS软件建立三角形及垂直排布三相双分裂线路有限元模型,对安装的间隔棒舞动防治效果进行模拟研究。模拟安装间隔棒前后线路在稳定风场及随机风场中的舞动响应;通过对比分析稳定风与随机风作用下导线位移响应及运动轨迹说明研究间隔棒防舞效果时考虑随机风场的必要性。基于随机风场中安装的间隔棒前后导线动力响应幅值,分析间隔棒对三角形、垂直排布双分裂线路舞动防治效果。Finite element models of three-phase transmission lines with triangular and vertical conductor arrangement were set up,and the anti-galloping efficiency of the interphase spacers mounted on the transmission lines was numerically investigated by means of the ABAQUS software.Galloping responses of the transmission lines in steady wind field and stochastic wind field were simulated,and the necessity to take the stochastic wind field into account in these analyses was illustrated through the comparison of dynamic responses of transmission lines in the two kinds of wind fields. The anti-galloping efficiency of the inperphase spacers on the transmission line with triangular and vertical conductor arrangement was analyzed based on the numerical simulation results.
