Paper Abstract

The impact of the mirror self-weight or other structural stress may cause bad optical imaging quality. The large-diameter primary mirror was optimized based on variable density topology optimization method and in the condition of gravity to satisfy the design requirements. A new primary mirror has been designed, comparing which with the traditional lightweight primary mirror in the method of finite element analysis, the results prove that the new primary mirror is superior to the traditional model in the lightweight rate, surface accuracy and structural rigidity, so the paper puts forward a new idea in the lightweight design.
