摘要

针对平单轴光伏支架风致扭转气动失稳问题，本研究采用全气弹模型，在风洞中复现了光伏支架的扭转气动失稳现象。通过对扭转响应和临界风速的分析，明确了平单轴光伏支架的风致振动特性。结果表明：光伏支架在-45°~45°的倾角范围内都可能发生扭转气动失稳，光伏组件水平放置时临界风速较高；小倾角下阻尼对临界风速影响较小，大倾角下增加阻尼可以提高临界风速；随着来流与光伏支架法线方向夹角(风向角)的增大，临界风速逐渐增加；斜风向下光伏支架尾流端部振动比迎风端部更剧烈。

Abstract

Aiming at the problem of wind-induced torsional aerodynamic instability of single-axis trackers, this study used a full aeroelastic model, and reproduced the phenomenon of torsional aerodynamic instability of the single-axis tracker in wind tunnel test. Through the analysis of torsional response and the critical wind speed, the vibration characteristics of the single-axis trackers are clarified. The results show that torsional aerodynamic instability occurs in the tilt angle range of -45°~45°, and the critical wind speed is higher in tilt angle of 0°，when the module is placed horizontally, than that in the other tilt angles . Damping has little effect on the critical wind speed at small tilt angles, and increasing damping at large tilt angle can increase the critical wind speed. With the increase of the angle between the incoming flow and the normal direction of the single-axis tracker (wind direction), the critical wind speed gradually increases. The vibration of the wake end of the single-axis tracker under oblique wind is more severe than that of the windward.
