Abstract

Swing system used in the guiding system is a kind of special equipment composed by a piece of silicon carbide mirror and a support structure made of Al alloy. In order to connect them without harm to their properties, epoxy resin is used and is solidified at room temperature. The influence of connecting process on the optical property of the mirror in swing system is studied by testing the wave-front error before and after connecting process. The results show that the connecting process under room temperature has little effect on wave-front error. The deformations of the mirror under gravity fields and thermal fields are analyzed by finite element method. The calculated results show that the surface figures under all conditions are satisfied with the requirement. The deformation of the mirror under gravity field paralleling to axial direction is the largest. When there is temperature gradient, the effect of axial temperature field on the mirror surface is much greater than that of radial temperature field.
