Optimum Design of the Support System of the SiC Primary Mirror with 1m Aperture

Abstract:

The support system of the one-meter SiC primary mirror was optimum designed by the finite element method. For the analysis, the 3D solid finite element model was used by the finite element software. The axial support-ring radius and the lateral support position were determined after the optimum design. The mirror deformations with different pitching angles were calculated. The maximum value of the surface figure deformation root-mean-square (RMS) is 23.84nm, which satisfies the requirement and shows the support system is reasonable and feasible.
