Abstract

The invention discloses a device and a method for automatically adjusting a loaded mass center of a platform surface of a single-shaft air floatation rotating platform and relates to a device and a method for adjusting a loaded mass center of a platform surface of a single-shaft air floatation rotating platform. The invention solves the problems of low adjusting efficiency and low accuracy of adjusting results of the traditional method for manually adjusting the loaded mass center of the platform surface of the single-shaft air floatation rotating platform. Four mass adjusting devices of the device are uniformly distributed and fixed at the edge of the air floatation rotating platform; a guide rail is disposed on each mass adjusting bracket; stepping motors fixed at one end of the guide rail drive a mass block to slide along the guide rail; the signal output end of an electronic level meter is connected with the signal input end of a control module; and the drive signal output end of the control module is connected with the drive signal input end of each stepping motor. In the method, the electronic level meter acquires and inputs platform surface levelness to the control module; and the control module drives four stepping motors to adjust the loaded mass center on the platform surface to be superposed with the center of the platform surface. The invention is suitable for adjusting the loaded mass center of the platform surface of the single-shaft air floatation rotating platform.

Description

technical field [0001] The invention relates to a device and method for adjusting the center of mass after the surface of a uniaxial air-floating turntable is loaded with an external load. 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 single-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 approximately 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-...
