线聚焦菲涅耳聚光器次级反射镜的仿真设计

摘要

This paper gives a small simulation concentrating design by using optical design software TracePro.Combining with theoretical study and simulation,the optical simulation test for the design is done by calculating and setting up the parameters of the tracing slope of flat mirrors,solar vector,and solar beam radiation.With the size 4×0.2m2 of flat mirror,the optimized design of the secondary reflector is suggested on the basis of the simulation result by changing the structural parameters of the type of the secondary reflector and the value of △H.%本文利用TracePro光学设计软件构建了一小型线聚焦菲涅耳聚光器仿真试验装置,理论研究与仿真实验相结合,通过计算和设置平面镜的跟踪倾角、太阳入射光线方向矢量、太阳直射辐射等参数,实现线聚焦菲涅耳聚光器光学仿真实验。在单块平面镜尺寸为4×0.2m2的情况下,通过改变次级反射镜的类型、次级反射镜与集热管间的距离△H等结构参数进行模拟,得出优化数据,提出聚光器次级反射镜的设计方案。
