  • As for the lightweight structure of a large-aperture primary mirror in remote sensors, this paper introduces an optimized multi-target Genetic Algorithm(GA) based on the Kriging approximate model to design all lightweight structure paramaters for a 2 m-aperture SiC primary mirror. The latin hypercube method is used to build the Kriging model and do the experimental design of optimized parameters, and then a optimal solution is obtained through the multi-target GA(NSGA II). After the optimization, the 2 m-aperture SiC primary mirror weights 243 kg, the surface accuracy reaches 25.7 nm PV, 4.7 nm RMS and the total lightweight rate is 84%. The experimental result proves the feasibility of this optimization method and it can be a reference for the future lightweight optimization design of the structural parameters of large-aperture primiary mirrors.
