Abstract

The invention relates to a device and method for automatically adjusting center of mass after applying load to a triaxial air-bearing turntable board. The invention solves the problems of high difficulty, low efficiency and low precision of the exiting method of manually adjusting the center of mass after applying load to the triaxial air-bearing turntable board. The device is characterized in that four mass adjusting devices are uniformly distributed on the edges of the air-bearing turntable board, with the center of the board as the origin; a mass adjusting device is fixed opposite to the vertical direction, wherein each mass adjusting support is provided with a guide rail; a stepping motor fixed at one end of the guide rail drives a mass block to slide along the guide rail; a signal output end of an electronic gradienter is connected with a signal input end of a control module; and a drive signal output end of the control module is connected with a drive signal input end of the stepping motor. The method comprises the steps of horizontal adjustment of the center of mass and vertical adjustment of the center of mass. The invention is suitable for adjusting the center of mass after applying load to the triaxial air-bearing turntable board.

Description

technical field [0001] The invention relates to a device and a method for adjusting the center of mass after the surface of a three-axis air-floating turntable is loaded. Background technique [0002] The semi-physical simulation of spacecraft control system is a unique simulation method in the process of developing spacecraft. It uses the air-bearing turntable as a motion simulator and combines the semi-physical simulation environment built by some real objects to carry out simulation verification of the control system scheme. The three-axis air-floating turntable uses compressed air to form an air film between the air-floating bearing and the bearing seat to make the table float in the air, and realize the approximate frictionless relative rotation between the air-floating turntable table and the table body, thereby simulating the spacecraft in outer space The mechanical environment with a small disturbance moment, and then use the rotation of the air-floating turntable on...
