Abstract

Design method led by high precision finite element analysis (H-FEA) and structural optimization platform is provided to obtain the support and the configuration of large aperture mirror. Firstly the mirror’s abstract model, whose configuration depends on several geometric parameters, is drawn by CAD software. Then the H-FEA is carried out to get the adequate FEM model balancing precision and computing cost. Afterward optimization of the abstract model is implemented. Finally the mirror’s detailed model is drawn and optimized parametrically. All procedures and iterations are driven automatically in an integrated flow without manual interruption. A 1.5 meter aperture mirror design example, achieving λ/12 PV and λ/56 RMS (λ=632.8nm), shows the effectiveness and practicability of the method.
