大跨度索结构光伏支架数值风洞模拟研究
Numerical Wind Tunnel Simulation Study on the Photovoltaic Bracket of Large-span Cable Structure
摘要
Abstract
Wind load is a key load for the photovoltaic bracket of large-span cable structure.In order to explore the influence law of wind load on the large-span photovoltaic structure,based on the computational fluid dynamics theory,the influence of the inter-group inclination angle θ and the wind direction angle on the wind load of the photovoltaic structure was studied through the numerical wind tunnel test method,and the distribution law and numerical results of the wind load were obtained.These were then quantified into the formula of the shape coefficient with the inclination angle of the photovoltaic module as the parameter and the table of the wind direction angle coefficient.The results show that the effect of the wind load on the surface of the module is strengthened with the increase of the inclination angle θ,and the influence law presents a nonlinear relationship.The influence law of the wind load can be fitted by a quad-ratic polynomial.The influence law of the wind direction angle can be directly incorporated into the wind load calculation formula as the wind load influence coefficient through normalization processing.The research results can provide a new reference basis for the determi-nation of the wind load coefficient of the photovoltaic bracket of large-span cable structure.关键词
