A superconducting translational magnetic levitation system based on superconductor complete diamagnetism

Abstract

The invention belongs to the field of high-temperature superconducting magnetic levitation, and is a superconducting translational magnetic levitation system based on superconductor complete diamagnetism, mainly including a superconducting translational magnetic levitation structure, a calibration device and a measuring device. Specifically, it is divided into superconducting flat layer, permanent magnetic floating platform, coolant container, small ball, arc guide rail, image acquisition equipment, and bracket. The complete diamagnetism of the superconductor under zero-field cooling eliminates the pinning of the magnetic flux, so that the translation of the permanent magnetic levitation platform is not hindered; The levitation force also reduces the influence of the superconductor splicing gap on the translational damping, the structure is simple and the feasibility is high; the size of the permanent magnetic levitation table is much smaller than the superconducting plane size, which reduces the edge effect of the superconductor and ensures the stability of the levitation force. The invention solves the problems of complex structure, large mass, large frictional damping and the like in the existing semi-physical simulation method of the air flotation platform.

Description

technical field [0001] The invention relates to the fields of micro-satellite physical simulation, damping force measurement and the like, in particular to a superconducting translational maglev system based on superconductor complete diamagnetism. Background technique [0002] With the continuous advancement of aerospace technology and the increasing requirements of space missions, microsatellites have begun to be widely used. Micro-thrusters used for micro-satellites have small thrust and high specific impulse, and can precisely adjust the orbit and attitude of satellites. In order to avoid thruster failure and ensure the reliability of the satellite's in-orbit operation, it is necessary to conduct a ground hardware-in-the-loop simulation test. However, the thrust-to-weight ratio of microsatellites is very small, which puts high demands on their ground testing.

However, the thrust-to-weight ratio of microsatellites is very small, placing high demands on their ground testing

[0003] At present, the common hardware-in-the-loop simulation equipment usually adopts an air-floating platform. However, the air-floating platform has a strong dependence on the gas working medium, cannot operate in a vacuum environment, and has a complex structure and a large volume, which greatly limits the measurement accuracy of the hardware-in-the-loop simulation platform. and sensitivity, which is not conducive to ground hardware-in-the-loop simulation of microthrusters
