Description

technical field [0001] The invention relates to a zero-gravity experiment system for a space multi-dimensional deployment mechanism. Background technique [0002] Zero gravity, also known as weightlessness or reduced gravity, is one of the most important features of the space environment. Before space systems such as satellites, aircraft and space stations fly in orbit, in order to ensure the high precision and reliability of the system, it is necessary to conduct dynamic tests on the subsystems of the space mechanism on the ground. However, the gravitational environment on the ground makes it impossible to obtain experimentally the functional performance characteristics of the mechanism. Therefore, the ground test of the space deployment mechanism needs to accurately simulate its zero-gravity environment. Only through the zero-gravity deployment test on the ground to fully verify the deployment function, deployment time, and locking position accuracy of the space deployme...
