【摘要】：太陽能光伏支架系統(tǒng)對風荷載比較敏感,其受到的風荷載成為設(shè)計中的主要控制荷載�，F(xiàn)階段對太陽能光伏支架系統(tǒng)風荷載的研究尚不夠成熟,各國規(guī)范只是粗略的給出結(jié)構(gòu)風荷載的取值范圍,但這些規(guī)定遠無法解決實際工程中太陽能光伏支架系統(tǒng)風荷載的問題。其風荷載特性與結(jié)構(gòu)本身的傾斜角度、底部阻塞度以及風場紊流度等參數(shù)有關(guān)系,因此研究太陽能光伏支架系統(tǒng)的風荷載分布規(guī)律對該類結(jié)構(gòu)的抗風研究意義重大。本文通過剛性模型測壓風洞試驗,研究了太陽能光伏支架系統(tǒng)風荷載分布的基本特點,分析太陽能光伏板的傾斜角度、離地高度、底部阻塞度以及來流紊流情況對結(jié)構(gòu)風荷載的影響規(guī)律,同時,研究太陽能光伏板上面積折減風壓系數(shù)的分布規(guī)律。對實際工程中類似結(jié)構(gòu)抗風設(shè)計具有一定的參考價值。全文主要包括以下內(nèi)容:(1)通過風洞試驗對均勻流場下太陽能光伏支架風荷載進行研究,給出典型工況下結(jié)構(gòu)的風壓分布特點,并總結(jié)出結(jié)構(gòu)風荷載受傾斜角度、風向角等參數(shù)的變化規(guī)律。(2)基于風洞試驗結(jié)果,分析結(jié)構(gòu)面積折減風壓系數(shù)的分布情況,并對傾斜角度、風向角等參數(shù)的影響進行說明。(3)通過不同紊流度及底部阻塞度時太陽能光伏支架風壓分布,給出阻塞度對體型系數(shù)的影響規(guī)律。
[Abstract]:Solar photovoltaic support system is sensitive to wind load and its wind load becomes the main control load in design. At present, the research on wind load of solar photovoltaic support system is not mature enough. However, these regulations can not solve the problem of wind load of solar photovoltaic support system in practical engineering. The wind load characteristics are related to the slope angle of the structure itself, the blocking degree at the bottom and the turbulence of the wind field. Therefore, it is of great significance to study the wind load distribution of the solar photovoltaic support system. In this paper, the basic characteristics of wind load distribution of solar photovoltaic support system are studied by rigid model pressure measurement wind tunnel test, and the tilt angle and height of solar photovoltaic panel are analyzed. At the same time, the distribution law of area reduction wind pressure coefficient on solar photovoltaic panels is studied. It has certain reference value for wind resistant design of similar structures in practical engineering. The main contents of this paper are as follows: (1) the wind load of solar photovoltaic support under uniform flow field is studied by wind tunnel test, and the wind pressure distribution characteristics of the structure under typical working conditions are given, and the inclined angle of wind load is summarized. Based on the results of wind tunnel test, the distribution of wind pressure coefficient of structural area reduction is analyzed, and the inclination angle is analyzed. The influence of wind direction angle and other parameters on the wind pressure distribution of solar photovoltaic scaffolds with different turbulence and blockage at the bottom is explained, and the influence law of blocking degree on shape coefficient is given.
