The invention relates to an oval reflector supporting device and a reflector assembly. The supporting device comprises a U-shaped groove, U-shaped two-pin support rod fixing ends, inclined rods and a reflector, external surfaces of the left and right sidewalls of the U-shaped groove are connected with the U-shaped two-pin support rod fixing ends via the inclined rods respectively, the left and right sidewalls of the U-shaped groove are provided with U-shaped two-pin support rod stress relief grooves respectively, and the inner surface of the U-shaped groove is provided with glue flowing grooves. The supporting device and the reflector assembly can be used to solve the technical problems that a present reflector assembly supporting device cannot ensure the deformation rigidity of a reflector surface under the load effect in the spatial heat environment and the damage intensity under the load effect in a vibration dynamic environment in the spatial emission process; and the reflector supporting device and the reflector assembly provided by the invention are low in weight, small in spatial occupation envelope size, feasible in technology, low in processing difficulty, easy to assemble and debug, capable of bearing harsh mechanical and thermal environments, and free of complex mechanical interfaces.
Description
technical field [0001] The invention belongs to the field of structural support of optical parts, in particular to a high-precision elliptical mirror support device and a mirror assembly. Background technique [0002] With the further development of space science and technology, the scope of use of space optical instruments is becoming wider and wider, and the requirements for use are getting higher and higher. In space optical instruments, the reflector is one of the essential key components. During the orbiting process, the weight of the reflector itself directly affects the launch cost and the surface shape accuracy of the reflector in the orbital working state with an exponential multiple relationship. And the pointing accuracy directly determines the performance of the instrument, so the design of the mirror and the performance of its supporting structure have important practical significance. [0003] Due to the complex launch and outer space environment, space optica...
