摘要： 通过风洞实验对平屋顶槽式聚光器的镜面风压进行测量,通过高阶矩与风压时程曲线和概率密度直方图对镜面风压分布的概率特性进行了分析;得到镜面风压分布的高斯判别标准,并给出典型工况下的镜面高斯区域划分。然后通过Sadek-Simiu（SAD）法计算出聚光器的极值风压系数,给出典型工况下的极值风压系数等值线图,并对极值风压系数分布规律和特征进行分析,镜面风压极值最大值出现的主要区域为镜面边缘角落区域,极值风压系数最大值出现的工况为仰角30°风向角45°,其值为6.136。

Abstract: In this paper, the mirror wind pressure of concentrator installed on flat roof trough is measured by wind tunnel experiment, and the probability characteristics of mirror wind pressure distribution are analyzed by high order moment and wind pressure time history curve and probability density histogram. The Gaussian criterion of mirror wind pressure distribution is obtained, and the division of mirror Gaussian region under typical working conditions is given. Then, the extreme wind pressure coefficient of the concentrator is calculated by Sadek-Simiu （SAD） method, and the contour map of the extreme wind pressure coefficient under typical working conditions is given. The distribution law and characteristics of the extreme wind pressure coefficient are analyzed. The maximum value of the mirror wind pressure is mainly in the corner area of the mirror edge, and the maximum value of the extreme wind pressure coefficient is 6.136 at the pitch angle of 30° and the wind direction angle of 45°.

Key words: solar concentrators, wind tunnels, roofs, probability distributions, extreme wind pressure
