摘要:为了保证在高的面形精度的前提下尽可能地降低硅镜的质量,通过对多种轻量化结构的分析与对比,确定了具体轻量化结构形式并对其进行了优化设计。通过计算机仿真分析证明了该优化设计方案的可行性,并采用超声加工方法实现了硅镜轻量化加工。试验结果表明:轻量化加工的硅镜镜体质量明显降低;虽然镜面精度有所降低,但仍能满足光学系统的设计要求。

Abstract: In order to reduce the weight of silicon mirror as much as possible under the premise of the highprecision of the surface,on the basis of analysis and comparison of a variety of lightholes, a specific structure was determined and its design was optimized. With computer simulation analysis, the design of optimization was proved to be feasible and it was implemented by the approach of ultrasonic machining.The results show that the weight of the Sic mirror is significantly reduced. Although the precision of surface lower slightly, it can be able to meet the design requirements of optical systems.It shows that optimization of the design is effective.
Key words: Sic mirror; lightweight structure; design of optimization; ultrasonic machining
