中文摘要:

为探究光伏跟踪支架的整体抗风特性，选取某光伏发电站单轴光伏跟踪支架作为工程背景。采用谐波叠加法模拟脉动风时程，运用流固耦合数值模拟，分析光伏支架在不同风向角下的风压分布和振动行为。研究表明：光伏组件表面的风压分布不均匀，组件边缘处风压最大；风向角对支架的位移响应有重要影响，顺风向和逆风向引起光伏支架不同程度的振动，在90 °侧风时，支架的横向位移响应最为显著；在光伏支撑组件中，檩条的位移最为显著；风载荷对支架上半部分和靠近主梁的部分影响较大。

英文摘要:

To investigate the overall wind resistance characteristics of photovoltaic (PV) tracking brackets, a single-axis PV tracking bracket from a photovoltaic power station in Hefei, Anhui Province, was selected as the engineering background. The harmonic superposition method was used to simulate the fluctuating wind time history, and fluid-structure interaction (FSI) numerical simulations were conducted to analyze the wind pressure distribution and vibration behavior of the PV bracket under different wind direction angles. The study revealed that the wind pressure distribution on the PV module surface is non-uniform, with the highest wind pressure occurring at the module edges. The wind direction angle significantly affects the displacement response of the bracket, with different levels of vibration induced in the downwind and upwind directions. At a 90 ° crosswind angle, the lateral displacement response of the bracket is the most pronounced. Among the PV support components, the purlins exhibit the most significant displacement. Additionally, wind loads have a greater impact on the upper part of the bracket and the areas near the main beam.
