Abstract

The invention discloses a uniform electromagnetic force field generation device and a method, which can be used for a space microgravity ground simulation experiment. A normal conductive liquid is used for magnetic mixing and suspension, a multi-point support is adopted, an excitation coil and a permanent magnet are designed, a multi-pole coupled electromagnetic field is generated, a needed electromagnetic force is provided in experiment space, the axial electromagnetic force at any point in an identical height and uncontrolled state is the same, a horizontal electromagnetic force is basically zero, and the electromagnetic forces of different heights in the space can reach a required constant value via an active control system. In the given three-dimensional experiment space, a constant electromagnetic force is generated for a moving body according to requirements, and the moving body is constantly in a microgravity simulation effect state. As for different experiment purposes and the moving bodies, the required constant electromagnetic forces are different, the size of the required uniform force field can be regulated and controlled via the active control system of the device, and different space microgravity ground simulation experiment requirements can be met.

Description

technical field [0001] The invention belongs to the technical field of ground simulation of microgravity in a magnetic-fluid mixed floating space, and relates to a uniform electromagnetic force field generation device and method. Background technique [0002] Magnetic levitation is widely used in ground microgravity effect simulation experiments. When the electromagnetic force on an object is equal to and opposite to the object's own gravity, the space weightlessness effect can be simulated. The electromagnetic force is mainly generated by superconducting magnetic levitation or electromagnetic levitation. This kind of ground microgravity simulation is mainly used in life science research, protein crystal growth, alloy molecule / refractory gold production, nano-magnetic liquid / fluid characteristics research, etc. [0003] There have been many studies on the control of the magnetic levitation system and its corresponding coupling, but there is no in-depth study on the time dela...
