Abstract

The invention relates to a microgravity effect ground simulation method based on magnetic-fluid mixed floating. The technical feature is that: based on the buoyancy of liquid, a mixed suspension mode of electromagnetic and liquid floating is used to provide means for accurately simulating space microgravity effects. Among them, most of the gravity of the object is overcome by the buoyancy of the liquid (coarse trim), and the remaining very small part of the gravity is overcome by fine-tuning the electromagnetic force (fine trim), so as to achieve the purpose of precise trim. At the same time, the adjustment of the levitation height of the object under the microgravity effect simulation environment controls the magnitude and direction of the electromagnetic force by controlling the current intensity or other electromagnetic field parameters, so as to realize the arbitrary change of the levitation height and position of the object under the weightlessness effect.

Description

A kind of microgravity effect ground simulation method based on magnetic liquid floating technology field The present invention relates to a kind of microgravity effect ground simulation method based on magnetic fluid mixed floating, relate to the ground simulation method of microgravity effect surface simulation method. Background technique The method of existing simulated microgravity environment / effect is mainly divided into two categories: (1) Utilize acceleration of gravity to create short-term weightlessness or microgravity environment, main means of realization comprises free fall Movement methods, such as the use of weightless aircraft, sounding rockets and microgravity drop towers (wells). (2) make test body continue to be subjected to the external force that can balance or approximate balance gravity, produce long-term microgravity effect The main realization methods are hanging wire gravity compensation method, air flotation method and neutral buoyancy met...
