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.
