To reduce the surface deformation of a star sensor reflector in complex and execrable environments.According to the circular optical reflector assembly,a micro stress flexible support structure was designed.By defining the thickness,width and radius as design variables,the flexible hinge in an circular reflector subassembly was optimized.Then,the surface figure precision,structural strength and dynamic stiffness of the reflector subassembly in the thermal-structural coupling state were analyzed with finite element method.Simulation results show that the natural frequency of the mirror is enough,which has a sufficiently high dynamic stiffness.
