An elliptical mirror support device and mirror assembly

Abstract

The invention relates to an elliptical reflector supporting device and a reflector assembly, comprising a U-shaped groove, a fixed end of a U-shaped bipod support rod, an oblique rod, and a reflector, and the outer surfaces of the left and right side walls of the U-shaped groove pass through The oblique bar is connected with the fixed end of the U-shaped two-leg support rod; U-shaped two-leg support rod stress relief grooves are arranged on the left and right side walls of the U-shaped groove, and glue flow grooves are arranged on the inner surface of the U-shaped groove. The invention solves the technical problem that the existing supporting device of the reflector assembly cannot guarantee the deformation stiffness of the mirror surface under the action of the space heat environment load and the strength of the damage under the action of the vibration dynamic environment load during the space launching process. The mirror support device and mirror assembly provided by the present invention are light in weight, small in space occupation envelope size, feasible in process, low in processing difficulty, simple in assembly and debugging, can withstand severe mechanical and thermal environments, and have no complicated mechanical interface.

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...
