Problems solved by technology

The three-axis air flotation table has strict requirements on the control of the center of mass of the table body. If a liquid storage tank is installed on the air flotation table, the change of the center of mass caused by the liquid sloshing in the storage tank during the test will affect the control of the air flotation table. downfall

Abstract

The invention provides a liquid sloshing moment simulation generator, which comprises control moment gyroscopes and an outer frame, wherein the outer frame comprises one or multiple frame shafts, andone or more control moment gyroscopes is / are arranged on the frame shaft(s); and the multiple control moment gyroscopes are distributed on multiple side surfaces of a pyramid shape. The invention alsoprovides a liquid sloshing moment simulation generation device and a simulation method thereof. According to the liquid sloshing moment simulation generator provided in the invention, a structure device for real-time generation of liquid sloshing disturbance torque is provided, the centroid changes during the rotating process are small, the device is applicable to a full physical simulation testfor a three-axis air floating platform, and a toppling phenomenon of the air floating platform can be avoided.

Description

Technical field [0001] The invention relates to the aerospace field and the field of simulation experiment devices, in particular to a liquid sloshing moment simulation generator, in particular to a liquid sloshing moment simulation generator suitable for full physical simulation of a three-axis air bearing table. Background technique [0002] In order to have the ability to break away from the gravity of the earth, enter the GEO transfer orbit or enter the transfer orbit between the planets, and reenter the planet, orbit the star, a spacecraft is generally equipped with a large liquid-filled storage tank, sometimes the amount of liquid fuel and the mass of the entire star. The ratio is as high as 50% to 60%, or even higher. Therefore, the coupling effect of liquid fuel sloshing and global control is greatly enhanced, which poses a severe challenge to the stability design of the control system. Especially in the orbit change maneuver section, because the engine is ignited and th...
