摘　　要：采用计算流体力学(CFD)理论建立了计算模型,对槽式太阳能聚热器不同角度、不同风速、聚热器板之间不同缝隙对风载荷的影响进行了分析。结果表明:聚热器随风速和角度变化对载荷影响较大,聚热器之间缝隙对风载荷影响几乎不变。Parabolic collector, an important equipment of the trough solar power, is quite sensitive to wind loads for it has a light and compact structure. It can fully grasp the exact figures of the wind loads exerting to the parabolic collector that counts. Therefore, the stent of the heliostat can be optimally designed. In this paper, the computational model of the parabolic collector is established according to the theory of Computational Fluid Dynamics （CFD）. The trough parabolic collector at different angles, different wind speed and the impacts of the gap between the different parabolic collector board on the wind load are calculated. The results show that the changes of the wind speed and angles of the parabolic collector have a great influence on the load while changing the gap between parabolic collector almost gets a constant wind load.
