Abstract

The invention discloses a ground integrated verification and test system for a spatial rotation mechanism based on the counteractive moment. The ground integrated verification and test system comprises a vacuum system, a low temperature system, a temperature control system, a rotary table system and a tool system; the vacuum system mainly comprises a vacuum container, a low vacuum system and a high vacuum system; the rotary table system is a uni-axis or tri-axis rotary table system; and the tool system is composed of a butt-joint trolley, a heating device fixing tool and a product fixing tool.The ground integrated verification and test system is simple in structure, convenient to move, install, debug and fix and easy to control, and can provide an integrated stress test environment for the vacuum, high temperature / low temperature / temperature change, and counteractive moment.

Description

technical field [0001] The invention belongs to the technical field of spacecraft reliability strengthening tests, and specifically relates to a ground comprehensive verification test system for a space rotation mechanism. Background technique [0002] In the field of aerospace technology, the rotating mechanism for spacecraft generally works in a coupling environment where two or more environmental stresses act simultaneously during the in-orbit service period, such as vacuum + high temperature, vacuum + low temperature, vacuum + temperature change, etc. Especially for aerospace electromechanical products (such as momentum wheels, control torque gyroscopes, etc.) that contain rotating mechanisms inside and have high pointing accuracy requirements or torque output characteristics, they also undergo satellite attitude adjustment maneuvers during the attitude adjustment process of the spacecraft. The reaction moment applied to the product. Therefore, such products are often u...
