Problems solved by technology

However, when the mirror diameter is relatively large, the influence of manufacturing errors on the mirror also increases accordingly, making the gravity surface shape seriously exceed the index requirements, which may lead to unusable supports that have been processed, which will bring time and economic costs. big loss

Abstract

The present invention provides a method for installing a mirror support assembly, which includes S1: simulating a designed installation model of the mirror support assembly, decomposing the surface shape index of the installation model of the mirror support assembly under different external disturbances, using It is used to judge whether the surface shape accuracy of the installed mirror support assembly is qualified; S2. Model the processed mirror body, and perform a center of gravity test, and correct the model according to the result of the center of gravity test to form a reverse mirror body. Model; S3. Simulate and analyze the reverse model of the mirror body, the flexure joint and the tapered sleeve together, obtain the axial positional relationship between the mirror body and the flexure joint, and determine the installation position of the flexure joint. The Monte Carlo analysis method adopted in the present invention judges whether the installation is qualified or not at an early stage, thereby effectively saving costs; in the assembly stage, considering the manufacturing errors encountered in the actual processing process, it is beneficial to obtain a high-performance camera that meets practical engineering applications.

Description

technical field [0001] The invention belongs to the technical field of space large-diameter reflector support design, and particularly relates to a method for installing a reflector support assembly based on three-point support on the back. Background technique [0002] With the increasing demand for astronomical observation and military-civilian earth observation, space cameras are developing in the direction of large aperture, large field of view and high image quality. In order to ensure that the imaging quality of the camera meets the index requirements under working conditions, it is necessary to consider reflections The imaging performance of the optical system when the mirror is subjected to various environmental disturbances. The lightweight design, flexible support design and component assembly technology of the mirror are the keys to the final imaging quality. The design of the reflector and its support is the premise to ensure that the performance of the componen...
