Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] The invention discloses an accurate tester for the magnetic repulsion force of superconducting blocks under tiny gaps, which belongs to the technical field of electromechanical test instruments and tribology test instruments, and is a basic parameter tester for the design of magnetic levitation kinematic pairs / friction pairs. It is mainly composed of double driving mechanism, permanent magnet chuck, superconductor chuck, liquid nitrogen cup, grating displacement sensor, S-type tension pressure sensor, bracket and so on. In this tester, in order to solve the two key problems of precise positioning of the superconducting block under the small gap and the precise measurement of the magnetic repulsion force of the small gap, a double drive method (fine-tuning nut + servo motor), a closed-loop control system and a high-precision sensor are adopted. (grating...

Abstract

Disclosed is an accurate tester of a superconductive-bulk magnetic-repulsion under a micro gap and a test method thereof. The tester mainly includes a double-driving mechanism, a permanent-magnetic chuck, a superconductor chuck, a liquid nitrogen cup, an optical grating displacement sensor and an S-shaped tension and pressure sensor. The tester adopts a double-driving method, a closed-loop control system and high-precision sensors to realize accurate positioning of a superconductive bulk and accurate measurement of a magnetic repulsion. The chuck structure realizes adaptive adjustment of a parallel degree of the permanent magnet-superconductor pair. The tester realizes 1mum measurement and positioning precision and 0.1 mum testing resolution so that blanks in measurement instruments of the magnetic repulsion of a superconductor bulk in the range of a micrometer gap are filled and thus testing demands for a kinematic pair/friction pair design in a micro gap in a maglev bearing can be met, and the tester has the advantages of being high in measurement precision, high in resolution and moderate in cost and the like and is worth adopting and popularizing; and the tester can also be used as a serialization product and used for teaching and scientific research of graduate students. The testing method has the advantages of being high in measurement precision, simple, convenient and practical and wide in applicable range and the like.

Description

technical field [0001] The invention belongs to the technical field of electromechanical testing instruments and tribological testing instruments, and in particular relates to an accurate tester for magnetic repulsion of superconducting blocks under tiny gaps and a testing method thereof. Background technique [0002] Due to its excellent magnetic field characteristics, high-temperature superconducting bulk materials have good application prospects in systems such as superconducting magnetic repulsion bearings and superconducting magnetic levitation trains. For these high-temperature superconducting systems, the levitation magnetic repulsion of the corresponding maglev kinematic pair / friction pair is the key factor to determine the stable operation of the system. Neglected, the measurement of its basic parameters has not been included in the field of tribology testing for a long time, and the improvement of national standards for corresponding testing instruments is also in ...
