Abstract

The invention provides a follow-up overhanging gravity compensation device based on magnetic suspension. The device mainly comprises a magnetic suspension drive compensation system and an overhangingcompensation system, the magnetic suspension drive compensation system comprises magnetic suspension drive modules and a magnetic suspension guide rail, and two magnetic suspension drive modules are respectively arranged on the magnetic suspension guide rail; the overhanging compensation system comprises an overhanging frame, overhanging constant force control modules and position servo modules, four supporting legs of the overhanging frame are respectively fixedly connected with the magnetic suspension drive modules, and two position servo modules are arranged on a sliding rail of the overhanging frame and respectively perpendicularly connected with two overhanging constant force control modules; each position servo module comprises two moving sliding blocks of an X direction, a moving sliding block of a Y direction, a servo motor, a screw and two auxiliary guide rods; each overhanging constant force control module comprises a direct current motor, a winding reel, a steel wire rope, an angle sensor and a tension sensor. The device has better comprehensive properties of simple structures, high gravity compensation precision, strong universality and good expandability.

Description

technical field [0001] The invention relates to a ground test device for a spacecraft, in particular to a gravity compensation device. Background technique [0002] Ground microgravity simulation is a research field emerging with the continuous development of aerospace technology. Human activities continue to develop into space, and the research on spacecraft is getting more and more in-depth. In the ground test equipment of spacecraft, the gravity compensation device is an indispensable part. The existing microgravity simulation methods mainly include: drop tower method, Parabolic flight method, water floatation method, air floatation method, suspension method and magnetic levitation method. [0003] The drop tower method is expensive, the size of the spacecraft is limited, the versatility is poor, and the time of a single microgravity experiment is too short to fully assess the various performance indicators of the spacecraft. [0004] The parabolic flight method is also...
