摘要

该文以某实际双层柔性光伏项目为工程背景

对其风振系数开展深入研究工作。首先设计制作气弹模型

并完成动力特性标定

进而开展风洞试验

探究不同风速、风向、边界条件等因素对结构风振系数的影响。然后建立双层柔性光伏支架结构的有限元模型

利用风洞试验结果验证仿真模型的可靠性

并分析气动阻尼、地面粗糙度、拉索索力等关键参数对结构动力响应及风振系数的影响。结果表明：结构的气动阻尼不可忽略;背风向风振系数大于正风向风振系数;风振系数与风速、拉索索力呈负相关

与地面粗糙度系数呈正相关。

Abstract

This paper takes a practical double-layer flexible PV project as the engineering background

an in-depth investigation into its wind-induced vibration coefficients was conducted. First

an aeroelastic model was designed and manufactured

and dynamic characteristics were calibrated. Subsequently

wind tunnel tests were conducted to investigate the influence of different factors such as wind speed

wind direction and boundary conditions on the wind-induced vibration coefficients. Then

a finite element model of the double-layer flexible PV bracket structure was established. The reliability of the simulation model was verified using the wind tunnel test results

and the influence of key factors such as aerodynamic damping

ground roughness and cable force on the structural dynamic response and wind-induced vibration coefficients was explored. The results indicate that the aerodynamic damping of the structure cannot be ignored. The wind-induced vibration coefficients in the leeward direction are greater than those in the windward direction. The wind-induced vibration coefficients are negatively correlated with wind speed and cable force

and positively correlated with the ground roughness coefficient.
