摘　　要：随着航空航天技术的发展,空间环境模拟的需求增多,太阳辐照模拟也备受关注。目前,较为成熟的太阳模拟器多为卧式太阳模拟器,其准直镜机构多采用拼接形式,而立式太阳模拟器具有节省空间的优势,其发展日趋成熟。根据太阳模拟器的总体要求,设计了一种应用于高辐照立式太阳模拟器的大口径俯视多维调节准直镜机构。根据高辐照、低背景工作环境特点,设计了多维可调节柔性吊装机构。为了提高系统的整体调试性能,采用单块整镜结构设计,降低了结构的复杂性。针对以上设计进行了计算及仿真分析,结果显示,柔性吊装机构可以有效平衡准直镜自身重力及环境温度造成的应力变形,最终满足太阳模拟器辐照度及辐照均匀性的使用需求。With the development of aerospace field,there exists an increase in the need of space environment simulation and solar radiation simulation has also attracted much attention.At present,most of the mature solar simulators designed and used are horizontal solar simulators,whose collimator mirrors usually adopt the form of splicing.However,the vertical solar simulators possess the advantage of space-saving and become gradually mature.In this paper,according to the general requirements of solar simulators,a large diameter overlooking multi-dimensional adjustable structure of collimating mirrors used for a high irradiation vertical solar simulator is designed.In addition,according to the characteristics of high radiation and low background working environment,a multi-dimensional adjustable flexible hoisting structure is designed.In order to improve the overall debugging performance of the system,a single-block whole mirror structure is adopted to reduce the structural complexity.According to the above designs,the calculation and simulation analysis are conducted and the results show that the flexible hoisting structure can be used to effectively balance the stress deformation caused by the collimating mirror′s own gravity and the environmental temperature,and finally to meet the use requirements of irradiance and irradiation uniformity for the solar simulators.
