摘　　要：以华中地区某500kV变电站联合构架为工程背景,探索全联合构架风致振动响应的计算方法,借助有限元分析软件ANSYS,以随机振动理论为依据,在频域内对500kV联合变电构架进行风致振动响应计算和分析,获得了该联合构架在0°、45°和90°风向角的不同风速的风荷载作用下,具有不同阻尼比的构架在基准高度处的位移均值响应分布和脉动响应分布规律,计算并分析了不同风向的风荷载作用下不同阻尼比的构架的风振系数与基准高度平均风速的定量关系。Taking a 500 kV transfer substation whole joint structure in the central Chinese provinces as the engineering background,a method for calculating the wind-induced vibration response of whole joint structure was explored.With the help of the finite element analysis software ANSYS,based on the theory of random vibration,the wind-induced vibration responses of the 500 kV whole joint structure in frequency domain were calculated and analyzed,through which the mean displacement response distribution and the pulsating displacement response of the frame with different damping ratios at reference height were obtained under the action of wind loads of 0°,45°and 90°direction angles,and under the effects of different mean wind speeds and damping ratios of frame.The quantitative relatinship between the wind-induced vibration coefficient of the frame with different damping ratios and the mean wind speed at the reference height was calculated and analyzed in different wind directions.
