Abstract Photovoltaic (PV) modules are mainly mounted on the ground and on roofs. Recently, cable-supported PV modules have been proposed to replace traditional beams using suspension cables to bear the loads of the PV modules. These modules have a long span, are lightweight, can bear strong loads, can be adapted to complex terrains, and provide an excellent supplement to traditional structures in special sites such as sewage treatment plants, highways, farms, fishponds, and roofs with poor load-bearing conditions. However, because the cable-supported PV modules also possess high flexibility and low damping, they are prone to large vibrations under wind excitation. In the present study, a series of wind tunnel tests were conducted to simulate the wind-induced vibration (WIV) of a type of cable-supported PV modules. Strong vibrations were observed when the wind speed was above a critical value. The response characteristics were investigated in detail, and a suppression measure was proposed according to the response characteristics. Finally, the proposed measure successfully suppressed the WIV of the cable-supported PV modules.

悬索支撑光伏组件的风振及其抑制

摘要 光伏（PV）组件主要安装在地面和屋顶上。最近，有人提出用缆索支撑的 PV 模块来代替传统的梁，使用悬索来承受 PV 模块的负载。这些模块跨度大、重量轻、承载能力强、适应复杂地形，是污水处理厂、高速公路、农场、鱼塘、承重较差的屋顶等特殊场所传统结构的极好补充。 -轴承条件。然而，由于电缆支撑的光伏组件还具有高柔韧性和低阻尼，它们在风激励下容易产生较大的振动。在本研究中，进行了一系列风洞试验来模拟一种电缆支撑光伏组件的风致振动 (WIV)。当风速高于临界值时观察到强烈振动。详细研究了响应特性，并根据响应特性提出了抑制措施。最后，所提出的措施成功地抑制了电缆支撑光伏组件的 WIV。
