Porous air-suspending supporting system applied to full physical simulation

Abstract

The invention relates to a porous air-suspending supporting system applied to full physical simulation. According to the air-suspending supporting system, a vacuum pre-load with volume reduction hills is adopted for being combined with a porous flow controller; and the porous air-suspending supporting system mainly comprises a vertical guide mechanism, an adjustable supporting transverse beam, a bearing sensor (17) and an air-suspending supporting mechanism (3), wherein the air-suspending supporting mechanism (3) is formed by an air-suspending supporting shell (23), air nozzles (19 and 20) and the porous flow controller (7). The air-suspending supporting shell (23) is formed by air-suspending pressure-sharing structures (7, 22, 24, 25 and 26), a negative pressure vacuum cavity (26) and the volume reduction hills (22). According to the porous air-suspending supporting system applied to full physical simulation, the anti-dumping force is increased so that the system can be more stable; and the system stability is further improved.

Description

technical field [0001] The invention relates to a porous air-suspension support system applied to full physical simulation, in particular to a porous air-suspension support system with vacuum preload. Background technique [0002] The attitude control of the spacecraft is the key to ensure the reliable operation of the spacecraft. In order to ensure the high precision and reliability of spacecraft operation, before the spacecraft deorbits, it is necessary to conduct dynamic testing experiments on the sub-systems of the spacecraft (such as antennas, solar arrays, radiators, and shields, etc.) on the ground. One of the most important features of the space environment is zero gravity. How to realize the working state of the test mechanism under the condition of weightlessness in the gravity environment of the ground environment has always been a difficult problem in the ground test of the space structure, which needs to be carried out on the ground. The full-physics simulation...
