摘要
由于太阳模拟器可以精确模拟太阳光, 近年来, 越来越多空间环境模拟试验采用太阳模拟器来模拟在轨高温环境。介绍了一个有效光束直径2 m的大型太阳模拟器, 其准直镜由19块正六边形的球面单元镜拼接而成; 分析了球面反射镜光学装调常用方法, 以球心自校准法为基础, 提出一种拼接式反射镜的装调方案; 详述了该拼接式准直镜的装调过程, 拼接后有效口径2 710 mm, 半径13 280 mm; 此外, 还介绍了大气环境下、真空低温环境下和真空热试验过程中大型太阳模拟器主要辐照特性检测方法及装置, 为太阳模拟器在工程中的更好应用提供参考。
Abstract
In recent years, because solar simulator can accurately simulate the sunlight, a growing number of space experiments apply solar simulator to simulate temperature environment on the ground. A large solar simulator with 2 m- diameter effective beam was introduced, and the collimator was made up of 19 unit spherical mirrors. Common alignment methods of spherical mirror were analyzed, and on the basis of spherical center self-collimated method, an alignment method of segmented collimating mirror was given. Alignment process was explained in detail and effective aperture was 2 710 millimeters and radius was 13 280 millimeters. In addition, radiation characteristics test methods and devices of the large solar simulator were also introduced, under atmospheric environment and in vacuum cryogenic environment and in vacuum thermal test, which provided reference for the better use of solar simulator in engineering.
