摘　　要：以柔性光伏支架结构为研究对象,基于气弹模型风洞试验,考虑风速、安装位置、风向角等参数的影响,研究柔性光伏支架阵列风致响应和稳定索对光伏支架的抑振效果。结果表明:柔性光伏阵列各排组件存在明显的干扰效应,来流方向第2、3排光伏组件在低风速(8~15 m/s)下极易发生尾流致振;光伏组件在风速较大时易发生颤振;0°、135°和180°风向角下,阵列迎风侧第1排首先出现颤振,颤振临界风速分别为18.0、22.5和16.2 m/s,随着风速的增大,结构颤振有向背风侧延伸的趋势,说明组件间的遮挡能提高结构的颤振临界风速。增加稳定索措施后结构整体性加强,可有效抑制光伏组件的尾流致振和颤振。Based on the aerodynamic model wind tunnel test,the wind-induced response of the flexible photovoltaic(PV)support array and the vibration suppression effect of the stability cable on the photovoltaic module were studied,considering the influence of wind speed,installation position and wind direction.The results show that there are obvious interference effects between each row of the flexible PV support array.The second and third rows of PV modules on the windward side are prone to wake-induced vibration at low wind speed(8-15 m/s).And this kind of structure is prone to flutter when the wind speed is high.Flutter first occurred in the first row on the windward side of the PV support array,and the flutter critical wind speeds were respectively 18.0,22.5 and 16.2 m/s at wind directions of 0°,135°and 180°.With the increase of wind speed,flutter tended to extend to the leeward side.It is indicated that shielding between modules could improve the flutter critical wind speed of the structure.After adding stability cable,the structural integrity can be strengthened,which can effectively suppress the wake-induced vibration and flutter of PV modules.
