A new quad bundle conductor galloping model considering wake effect is proposed to solve the problem of different aerodynamic coefficients of each subconductor of iced quad bundle conductor. Based on the quasistatic theory, a new 3-DOF (three degrees of freedom) galloping model of iced quad bundle conductors is established, which can accurately reflect the energy transfer and galloping of quad bundle conductor in three directions. After a series of formula derivations, the conductor stability judgment formula is obtained. In the wind tunnel test, according to the actual engineering situation, different variables are set up to accurately simulate the galloping of iced quad bundle conductor under the wind, and the aerodynamic coefficient is obtained. Finally, according to the stability judgment formula of this paper, calculate the critical wind speed of conductor galloping through programming. The dates of wind tunnel test and calculation in this paper can be used in the antigalloping design of transmission lines.

考虑唤醒效应的冰四方捆扎导体的舞动稳定性和风洞试验

提出了一种考虑尾流效应的新型四束导体疾驰模型，以解决冰四束导体各子导体空气动力学系数不同的问题。基于准静态理论，建立了一种新的三自由度三自由度冰激凌四束导体的舞动模型，该模型可以准确地反映四束导体在三个方向上的能量传递和驰豫。经过一系列的公式推导，得出导体稳定性判断公式。在风洞试验中，根据实际工程情况，设置了不同的变量，以准确模拟风中冰四极管导体的舞动，并获得了空气动力系数。最后，根据本文的稳定性判断公式，通过编程计算导体疾驰的临界风速。本文的风洞试验和计算日期可用于输电线路的防振设计。
