摘　　要：引起太阳能光伏板及其支架风致损坏的一个主要原因是其抗风设计方法尤其是风荷载取值模型仍不够完善。通过刚性模型测压风洞试验得到的光伏板表面体型系数分布规律及其产生的整体风荷载,提出了考虑光伏板倾角及风致弯矩影响的四角点平面风荷载分布模型及偏心距模型。结合光伏板的结构特点,给出了均匀分布、梯形分布和偏心距三种用于抗风设计的风荷载取值模型。该研究分析了目前风荷载取值模型的不足并提出了改进措施,通过三种风荷载分布模型的对比,为光伏板抗风设计的风荷载取值提供了依据。A primary reason for wind induced failure of a solar panel and its support structure is the imperfect method for its wind resistance design, especially, the wind load distribution model. Through a rigid model pressure test in a wind tunnel to obtain the distribution law of shape coefficients of the solar panel surface and the whole wind load on the solar panel, a four-corner-distribution model and an eccentric moment model considering effects of both inclination and wind induced moments were proposed. Three wind load models including uniform distribution model, trapezoidal distribution one and eccentric moment one were given in term of structural features of a solar panel. Deficiencies and improvement measures of wind load models used currently in the solar panel design were analyzed. Through comparing the three wind load models mensioned above, a guidance was provided for correctly choosing wind load in the anti-wind design of solar panels.
