摘要
该文在文献[1]的基础上,通过对太阳能定日镜反射板的实际工作状况及有限元分析,分别采用薄板大、小挠度弯曲理论研究反射板的挠度及应力规律,给出定日镜反射板周边固支矩形薄板弯曲力学模型;经理论分析及算例验证表明:太阳能定日镜反射板的合理力学模型应为周边固支矩形薄板小挠度弯曲力学模型;并根据反射板结构的受力情况及材料特性,从刚度和强度条件出发,提出反射板厚度的设计方法。
Abstract： On the basis of the paper of ＂Deflection for Reflector Plate of Heliostat Based on Thin Plate Flexure The- ory＂, the model of rectangular plate with periphery fixed was proposed according to the actual working condition of reflector plate. The deflection and stress of reflector plate were respectively studied on the basis of large-deflection and small-deflection thin plate flexure theory. Theoretical and instantial analysis indicated： clamped rectangular plate based on small-deflection thin plate flexure theory was the reasonable model for reflector plate; thickness of reflector plate could be rationally designed in reference to the stiffness and intensity conditions of material properties and stress characteristics.
