Abstract

The invention relates to an air floating platform with follow-up cable tables, belonging to the technical field of simulation testing equipment of spacecrafts and solving the problem that the existing air floating platform runs for a short time due to the limited capacity of an air supplying high pressure gas cylinder. The air floating platform comprises five parts, namely, air flotation, measurement, follow-up cable tables, an object stage and an upper computer, wherein all parts on a base are in air flotation state, the two follow-up cable tables are used for providing interfaces for an external gas circuit and an external circuit, so as to guarantee the continuous simulation work without limitation to running time, two position sensors are respectively used for detecting relative position relationship between two parts, the upper computer controls air injection of the nozzle of each part so as to keep the equipment synchronization. The air floating platform is the simulation testing air flotation platform of the spacecraft.

Description

technical field [0001] The invention relates to an air bearing platform with a moving cable platform, and belongs to the technical field of simulation test equipment for spacecraft. Background technique [0002] Today, one of the main directions of competition between major powers is the competition of space resources, which depends on the development of spacecraft. Before the spacecraft is launched, it must undergo a ground simulation test to test its performance. As a result, higher and higher requirements are put forward for the test environment of the spacecraft simulation test, which needs to provide a test environment similar to the microgravity and micro-interference in outer space. [0003] In the test environment of the spacecraft simulation test, the air flotation platform is usually used as the control object to simulate the spacecraft body. The way the bottle controls the nozzle ensures the formation of an air film between the air flotation platform and the air...
