Abstract
The utility model discloses an air-floating platform, which comprises an air-floating platform, a high pressure air source, and a simulating platform. The high pressure air source provides high pressure air for the simulating platform and keeps the simulating platform floating above the air-floating platform under the action of the high pressure air; the simulating platform comprises a platform body and at least three air-floating blocks which are arranged on the lower part of the platform body; the high pressure air source is connected with the air-floating block through pipelines; and a resultant force produced by each air-floating block under the action of the high pressure air is acted on the gravity center of the simulating platform. The air-floating platform of the utility model leads the simulating platform to float by depending on an air membrane formed between the air-floating platform and the air-floating block, thus providing a frictionless state so as to simulate a mechanical environment that a satellite has a very small disturbing torque in an outer space, and creating conditions for the simulation test of the satellite.
