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...
