摘要
柔性光伏支架以其独特的大跨度和高净空设计,为光伏电站的建设提供了一种高效且环境友好的解决方案。为完善此类光伏支架结构的抗风设计方法,通过对一种可变倾角的大跨柔性光伏支架结构进行气弹性模型风洞测压试验,以三跨四排大跨度柔性光伏支架为研究对象,对大跨度柔性光伏支架风振响应及风振系数进行研究。研究结果显示:随着风速的升高,光伏支架结构的振动响应呈现逐渐增大的趋势,特别是在较高风速下,风力对结构振动的影响显著;180°风向角下,结构的风致振动更为明显,对结构的破坏程度最大。
Flexible photovoltaic supports,with unique large-span and high-clearance design,provide an efficient and environment-friendly solution for the construction of photovoltaic power stations.To improve the wind resistance design method for such flexible photovoltaic supports,an aeroelastic model wind tunnel pressure test is conducted on flexible photovoltaic supports with variable inclination angles.Based on a three-span and four-row large-span flexible photovoltaic bracket as the research object,the study investigates the wind vibration response and wind vibration coefficient of the large-span flexible photovoltaic supports.The research results show that as wind speed increases,the vibration response of flexible photovoltaic supports gradually increases,especially at higher wind speeds,where the impact of wind force on structural vibration is significant.Under different wind direction angles,especially at 180°wind direction angle,the wind-induced vibration of the structure is more pronounced,leading to the most significant degree of structural damage.
