摘要
提出了一种采用柔性支撑的大口径反射镜组件进行遥感器地面检测的装置。通过有限元分析对反射镜的支撑结构、形状尺寸、轻量化孔的形状、尺寸及分布位置进行计算,得到了一种合理可行的支撑结构。在该支撑结构下面形精度达到λ/40(λ=632.8nm),满足遥感器地面检测的精度要求。
A kind of flexible structure applied to support the large aperture mirror is put forward for space remote sensing.With FEA method,the features such as support structure,size,the shape of the lightweight hole and weight distribution are calculated to obtain the feasible and reasonable structure.The result shows that the mirror surface figure precision can reach λ/40(λ=632.8 nm) in the structure,and can meet the needs of remote sensing precision.
