In order to design a large aperture primary mirror with the diameter of 1150 mm  the parameters impacting on gravity deformation of the mirror were analyzed and discussed in detail  including material selection  diameter-thickness ratio  the number of the support points  location selection and lightweight structure  etc. A novel space mirror structure system was put forward  and its back was opened and supported by six points on back. The dynamic and static and thermal characteristics were analyzed based on the finite element method. Analysis results showed the surface figure accuracy reached to RMS 14.5nm under the action of gravity load along the optical axis direction and the first-order natural frequency was 214Hz which met to the designed indexes requirements.

This paper introduced a kind of reflector mirror support structure of IRST system. Thescanning reflector mirror support frame material is Ly2 aluminum under the principle of the suited ofmaterial expanding quotient. The support form of the reflector was talked  and the system bracketstructure was designed following the requests of the certain complex IRST. The bracket wasoptimized and analyzed under the best structure quality and the least moment of inertia  and thebellowing of bracket plane thickness  mode frequency restriction and deadweight restriction. Fromthe result we can see that the bracket mass can reduce from 0.73kg to 0.49kg and the moment ofinertia can reduce from 0.0109kg2 to 0.0056 kg2 under the first precondition of the structure modefrequency being low and the biggest transmogrification being teeny. The base frequency and intensionof the complex IRST system can be indicated well after the finite element analysis static checking. (2011) Trans Tech Publications  Switzerland.
