摘　　要：采用AR线性滤波法与Davenport脉动风速谱相结合的方法,通过开展风速、光伏面板倾角对支架风振系数影响的敏感性分析,探讨了固定式光伏支架在不同环境下的风致响应。结果表明固定式光伏支架各部件的风振系数基本一致;支架的风振系数取值与光伏面板倾角无明显相关性;当风速位于24 m/s~30 m/s之间,风振系数可取1.4,对应于基本风压为0.36 kN/m^(2)~0.56 kN/m^(2)。This paper adopts a method combining AR linear filtering with Davenport’s fluctuating wind speed spectrum.By conducting sensitivity analysis on the impact of wind speed and photovoltaic panel inclination on the wind-induced vibration coefficient of the support,it explores the wind-induced response of fixed photovoltaic supports under different environments.The results show that the wind-induced vibration coefficients of each component of the fixed photovoltaic bracket are basically the same;There is no significant correlation between the wind-induced vibration coefficient of the bracket and the inclination angle of the photovoltaic panel;When the wind speed is between 24 m/s~30 m/s,the wind vibration coefficient can be taken as 1.4,corresponding to a basic wind pressure of0.36 kN/m^(2)~0.56 kN/m^(2).
