摘要

利用风洞试验测量四分裂导线的空气动力系数，得到各子导线的空气动力系数随风攻角的变化曲线，表明尾流干扰对处于上风子导线尾流区的子导线的气动特性影响明显。给出利用ABAQUS有限元软件模拟分裂导线尾流驰振过程的方法，进而针对典型四分裂导线线路段，模拟得到包括整档舞动和次档距振动的尾流驰振现象，分析了整档舞动和次档距振动的特征，以及间隔棒不同布置方式和风速对尾流驰振的影响。

Abstract

The aerodynamic coefficients varying with angle of attack are measured with wind tunnel tests. It is shown that the aerodynamic characteristics of a sub-conductor locating at the wake zone of another sub-conductor are apparently affected by the wake interference. Wake galloping including full span galloping and sub-span oscillation of a typical quad bundle conductor line is numerically simulated by means of ABAQUS software. The effects of mounted spacers with non-uniform and uniform arrangement schemes and wind speeds on the wake galloping characteristics of the line are analyzed.
