摘　　要：风荷载是在太阳能聚光碟结构设计时要考虑的重要载荷之一,通过对聚光碟结构加载脉动风荷载,可以直观了解太阳能聚光碟结构的动力学特性,为聚光碟等结构抗风设计的研究做基础。本文以某4.5m太阳能聚光碟发电系统结构的动力学问题为背景,用MATALAB软件对脉动风速时程进行绘制,再将模拟得到的脉动风速功率谱与目标值进行对比,以检查模拟结果是否可行。One of the important load wind load is polyethylene disc structure to be considered in the de-sign of solar energy through the structure of the polymer discs loaded fluctuating wind loads, you can intu- itively understand the dynamics of the solar disc structure of polyethylene, polyethylene discs and other structural study of wind Design foundation. Dynamics Taking a 4.5 m concentrated solar power system disc structure as the background, through the preparation of fluctuating wind speed time MATALAB and compared to simulate the power spectrum of fluctuating wind speed and the target value, check the feasi- bility of the simulation results.
