摘要
对用于空间光学仪器的镜子实施轻量化工艺的必要性作了阐述,并对轻量化镜子的材料及结构的选择作了讨论。用有限元计算法对轻量化镜子在外力作用下的变形情况进行了计算分析。最后,文中还具体介绍了镜子实施轻量化技术后的结果。
The necessity of lightening the weight of the mirror for spaceoptical instrument is stated in this paper.The selection of material andstructure of lightweight mirror is also discussed.The deformation oflightweight mirror resulting from the external forces acting on it iscalculated using the finite element method.Finally the performances of theweight-lightened mirror are described.
