A zero-gravity experimental system for space multi-dimensional deployment mechanism

Abstract

The invention discloses a zero-gravity experiment system for a spatial multi-dimensional unfolding mechanism. The zero-gravity experiment system comprises an analog wall (1), an unfolding rack (2), a rocker arm hanging device and an air floatation vehicle device, wherein the spatial multi-dimensional unfolding mechanism consists of a big arm (13), a small arm (14) and a load (15); the analog wall (1) is used for fixing the spatial multi-dimensional unfolding mechanism; one end of the big arm (13) is movably connected to the analog wall (1), and the other end of the big arm (13) is hinged to the small arm (14); the small arm (14) is fixedly connected with the load (15); the rocker arm hanging device is arranged on the unfolding rack (2) and can rotate opposite to the unfolding rack; the rocker arm hanging device can hang the big arm (13); the load (15) is positioned on the air flotation vehicle device. According to the experiment system, the unloading resistance is small, and the unloading efficiency reaches 95 percent.

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...
