The wind-induced vibration characteristics of the photovoltaic support system are investigated from a time-domain analysis perspective, offering valuable insights for the wind resistance design of array photovoltaic tracking supports.
(1) Background: As environmental issues gain more attention, switching from conventional energy has become a recurring theme. This has led to the widespread development of photovoltaic (PV) power generation systems. PV supports, which support PV power generation systems, are extremely vulnerable to wind loads.
The wind-induced vibration caused by wind loads is one of the main reasons for the failure of PV supports, so the research focus is not only to improve the power generation efficiency of PV systems but also to reduce the wind-induced vibration of PV support structures.
(2) Methods: First, the effects of several variables, including the body-type coefficient, wind direction angle, and panel inclination angle, on the wind loads of PV supports are discussed. Secondly, the wind-induced vibration of PV supports is studied. Finally, the calculation method of the wind load on PV supports is summarized.
Wind-induced vibration plays a crucial role in the design of flexible PV support structures, impacting both structural safety and energy conversion efficiency. This study develops an efficient
