摘要
薄膜相机由于其薄膜主镜的高分辨率、轻量化及体积小等特点,广泛应用在高空环境中。但是,薄膜受高空环境影响易产生形变,降低成像质量。我国研究人员主要通过实验的手段来复现高空环境并进行薄膜成像分析,导致薄膜相机的研发成本提高、研发周期增大。为了节约资源、降低产品研发成本及研发周期,应用计算机仿真技术,通过模拟薄膜相机在高空的工作环境,采用有限元分析软件,设置不同的仿真条件,得到薄膜结构的不同变化,分别对薄膜主镜进行了数据采集和对比分析,得到了薄膜在中心固定约束下最符合实际工作情况。
Film cameras are widely used in high-altitude environments due to the high resolution, light weight and small size of the film primary mirror. However, the film is easily deformed by the high-altitude environment, which reduces the imaging quality. Chinese researchers mainly use experimental methods to reproduce the high-altitude environment and conduct thin-film imaging analysis, which leads to the increase of the R&D cost of the film camera and the increase of the R&D cycle. In order to save resources and reduce product R&D cost and R&D cycle, this paper applies computer simulation technology through the simulation of film camera in high altitude working environment, and uses finite element analysis software to set different simulation conditions to obtain different changes in the film structure. Data acquisition and comparative analysis are performed for the film main mirror, and it is obtained that the film is most suitable for actual working conditions under the center fixed constraint.
