Mass compensation system of gas floatation planar motion platform

Abstract

The invention discloses a mass compensation system of a gas floatation planar motion platform, and belongs to the field of full-physical ground simulation. To solve the problems that change of the weight of high-pressure gas in a gas bottle arranged on the platform can cause change of the load mass of the upper platform surface and consequently simulation tests can be influenced, the mass compensation system is composed of a first water storage cavity, a second water storage cavity, a water pump and conveying pipelines, wherein the first water storage cavity is hung to the lower end of an upper platform body of the six-degree-of-freedom gas floatation platform, the second water storage cavity is arranged on a lower platform body of the six-degree-of-freedom gas floatation platform, and the first water storage cavity and the second water storage cavity are connected with the water pump through the conveying pipelines. According to the mass compensation system, the mode of dynamic compensation through the two water storage cavities is adopted, and after the mass of lost gas in the gas bottle is measured, balance weight liquid with the same mass is pumped into the water storage cavity of the upper platform body through the water pump. The mass compensation system guarantees the mass stability of a bearing platform and greatly improves the precision and feasibility of the simulation tests.

Description

Technical field [0001] The invention belongs to the field of ground full physical simulation, and relates to a mass compensation system for an air-floating plane motion platform.
