Superconducting magnetic levitation and static suspension mixing suspension supporting arrangement

Abstract

The invention provides a superconducting magnetic levitation and static suspension mixing suspension supporting arrangement, and six support modules (9) are symmetrically distributed on a reference axis of orthogonal coordinate system whose original point is the center of a rotor chamber (8). A superconductive rotor (10) is located in a rotor chamber (8). A magnetic field generated by a superconducting coil (11) after excitation enters from a gap between a superconductive shaping block (12) and an inner superconducting ring (13) into a gap between the superconductive shaping block and the superconductive rotor (10), and then returns from a gap between the superconductive shaping block (12) and an outer superconducting ring (15) as well as the lower part of the superconducting coil (11) to the gap between the superconductive shaping block (12) and an inner superconducting ring (13), thereby forming a closed magnetic circuit. A support electrode (14) is enclosed by an inner superconducting ring (13). A magnetic field generated by the superconducting coil (11) produces a magnetic repulsion for the superconductive rotor (10), and a supporting voltage applied by a support electrode (14) produces for an electrostatic attraction for the superconductive rotor (10), and the total suspension force which is applied to the superconductive rotor (10) is the resultant force of the magnetic repulsion and the electrostatic attraction.

Description

technical field [0001] The invention relates to a superconducting magnetic suspension supporting device, in particular to a hybrid suspension supporting device of superconducting magnetic suspension and electrostatic suspension. Background technique [0002] Inertial navigation technology is an autonomous navigation technology that does not depend on any external information and does not radiate energy to the outside. Its core component is a gyroscope. The gyroscope is the sensor of the motion of the vehicle, which can maintain the stability of precise pointing in the inertial space. However, in some special occasion applications, not only the navigation system is required to have high precision, but also high impact resistance is required, which is directly related to the reliability of the navigation system, which directly depends on the support system of the gyroscope performance. In order to reduce the influence of interference torque and improve measurement accuracy, ...

AI Technical Summary

Problems solved by technology

When the superconducting magnetic levitation support system is subjected to excessive impact interference force, the local magnetic field strength in the support gap may exceed the lower critical magnetic field strength of the superconductor and cause the support system to fail

The superconducting magnetic levitation device of Chinese patent 201210023048.5 adopts a single superconducting magnetic levitation method. When the carrier of the magnetic levitation device is disturbed by a severe impact, the magnetic field around the superconducting rotor may exceed the critical magnetic field of the superconducting rotor, causing the superconducting rotor to quench , resulting in the failure of the support system

The literature [W.J.Bencze, M.E.Eglington, R.W.Brumley, S.Buchman.Precision electrostatic suspension system for the Gravity Probe B relativity mission's science gyrogropes, ADVANCES IN SPACE RESEARCH, 2007,39:224-229] gives a low-temperature electrostatic suspension The support device, the rotor is in a superconducting state, and the suspension force is provided by electrostatic attraction. The suspension support device can only withstand a disturbance acceleration of 1g in the working state, which obviously does not satisfy some occasions where the impact disturbance force is relatively large

Therefore, whether it is an electrostatic levitation support or a superconducting magnetic levitation support, the overload capacity of a single levitation support is limited by objective technical conditions and physical principles, and may not be able to meet the application requirements in certain specific environments.
