摘要:
为了研究可充气聚焦器的展开过程及展开后的性能,以一个开口面积为20 m2,焦距为8 m的旋转抛物面型太阳能聚焦器为例建立了充气结构模型,采用控制体积法对一次和三次折叠的未充气状态的支撑杆及反射部件的展开过程进行了仿真计算。基于充气反射面展开后的几何模型,采用蒙特卡罗光线跟踪法,数值模拟了其对光线的聚焦性能。结果表明展开后的反射面聚焦效率约为理想设计曲面的57%,褶皱是其聚焦性能不高的主要原因。分析展开后结构的聚焦效率可以作为评价可充气展开结构展开性能优劣的一种新方法。
Abstract:
To study the deployment process and deployed characteristics of the inflatable concentrator,a paraboloidal dish concentrator,whose aperture and focal length are 20 m2 and 8 m respectively,is built and taken as an example.The deployment of the one-fold and three-fold inflatable support truss and reflecting part is simulated with the control volume method.Based on the geometrical model of a deployed reflecting surface,the concentrating characteristics on the receiving plane are performed with the Monte Carlo ray tracing method.The results show that the concentrating efficiency of the deployed structure is 57% of the designed one,and the low concentrating efficiency is mainly caused by the wrinkling of the reflecting surface.Analysis of unfolded structure ’ s concentrating efficiency can be as a new method to evaluate the deployment performance of deployable structure.
