Abstract

A satellite accessory vibration flexible moment simulator based on a balance beam relates to a moment simulator and is used for settling the problems of inaccurate moment control, small control range and small moment in existing equipment for realizing semi-physical simulation on flexible satellite attitudes. The satellite accessory vibration flexible moment simulator comprises a base, three balance beam systems and three circular raster systems. The three balance beam systems are vertically configured and are assembled for forming a three-shaft moment generating mechanism which is mounted on the base. Each balance beam system comprises a balance beam, a driving mechanism, a base and two counterweight blocks. The length directions of two random balance beams in the three balance beams are perpendicular with each other. Each driving mechanism comprises a motor, a motor base, a motor connecting block and a shaft. The motor on each balance beam system is mounted on the motor base. The motor bases are mounted on the base. The output end of each motor is provided with a motor connecting block. The satellite accessory vibration flexible moment simulator is used for developing satellites.

Description

technical field [0001] The invention relates to a moment simulator, in particular to a flexible moment simulator. Background technique [0002] Semi-physical simulation of satellite control system is a unique simulation method in the process of satellite development. It uses a single-axis air-floor table as a motion simulator, also known as air-floor table simulation. The semi-physical simulation of the satellite control system uses a single-axis air bearing table to simulate the satellite body as the control object, and the control system uses the satellite control system for simulation. When a space vehicle performs semi-physical simulation, it is necessary to simulate important space environments such as weightlessness or no resistance on the ground. [0003] In the semi-physical simulation of the existing general flexible satellite attitude, the simulation is carried out in the form of installing a stretchable flexible board on a single-axis platform. The method of ins...
