Abstract

The invention relates to a method for improving optic loading imaging quality, in particular to the method for using a multistage vibration isolation platform to improve the optic loading imaging quality, and belongs to the field of high-frequency vibration control. The vibration isolation platform comprises an upper platform, a lower platform and a support rod for connecting the upper platform and the lower platform. The vibration isolation platform can be installed on a flywheel or a control moment spinning top and the like between a satellite actuating mechanism and a satellite star or between an optic payload and the satellite star. The control moment spinning top, an installation support and the upper platform of the vibration isolation platform jointly form an upper platform system. When the optic payload and the satellite star are needed for loading the vibration isolation platform, a base of the optic payload is fixedly connected with the upper platform of the vibration isolation platform to form a set of the upper platform system. The lower platforms of all vibration isolation platforms are fixedly connected onto the satellite star to jointly form a lower platform system. The method solves the problem that imaging accuracy and stability of the optic payload on a star are low.

Description

technical field [0001] The invention relates to a method for improving the imaging quality of an optical load, in particular to a method for improving the imaging quality of an optical load by using a multi-stage vibration isolation platform, and belongs to the field of high-frequency vibration control. Background technique [0002] At present, the main vibrating components on spacecraft are actuators with high-speed rotors such as flywheels or control moment gyroscopes. Their vibration is mainly caused by the static and dynamic unbalance of the high-speed rotor and the installation error of the mechanical bearing, and the resulting vibration will directly affect the imaging quality of the optical load. Combining a Design Method of Flywheel Attitude Control System for Flexible Aircraft (Geng Yunhai, Cui Hutao, Cui Haiying, Yang Di. Design of Flywheel Attitude Control System for Flexible Aircraft[J]. System Engineering and Electronic Technology. 2001, 23(6) :55-58), and addi...
