A method of connecting satellite cabins under over-constrained conditions

Abstract

The invention provides a satellite inter-module connection method under over-constrained conditions, comprising: a maglev mechanism, a one-off unlocking device and a maglev mechanism tool mounted on aplatform module roof. The electromagnetic sucker end of a repeatable unlocking device and a repeatable unlocking device tool are mounted on the platform module roof; the suction end of a re-connectable release device is mounted on a load module suspending plate; the load module suspending plate is mounted above the platform module roof; the maglev mechanism is connected with the load module suspending plate; after the maglev mechanism tool is released and the load module suspending plate is lowered, the bottom of the load module spending plate is in contact with the top of the repeatable unlocking device tool; the one-off unlocking device is connected with the lateral side of the load module suspending plate, and the repeatable unlocking device tool is released. The method herein has theadvantages that the steps are clear, assembly is simple, the demand for reliable connection of two modules can be met under the over-constrained conditions, and the method is applicable to sun-oriented solar observation tasks having high requirements on attitude precision and stability.

Description

technical field [0001] The invention relates to the field of aerospace components, in particular to a connection method between satellite cabins under over-constraint conditions. Background technique [0002] With the development of space detection technology in the direction of higher (sensitivity), more precise (resolution), and stronger (multi-task, multi-function), the pointing accuracy and stability of the solar observation payload to the satellite platform are getting higher and higher. The traditional satellite payload is fixedly connected to the platform, which is affected by flexible accessories, and micro-vibration is difficult to measure and control, which seriously limits the pointing accuracy and stability of the satellite. Through the magnetic levitation mechanism, the space separation between the load compartment and the platform compartment can be realized, the micro-vibration effect of the platform compartment can be eliminated, and the high pointing accurac...

Problems solved by technology

[0003] However, when the satellite is launched on the ground, it is necessary to achieve a fixed connection between the two cabins. When in orbit, the two cabins need to be equipped with multiple maglev mechanisms to achieve on-orbit attitude control. When the orbit is maneuvering, the two cabins need to be reliably connected. It is necessary to configure stand-alone machines such as maglev mechanism, one-time unlocking device, and repeatable unlocking device. These stand-alone machines need to be connected with the two cabins, resulting in a large number of constraints and difficult assembly
