Problems solved by technology

Since the circular permanent magnet track has a certain curvature, which is different from the actual permanent magnet track, the dynamic performance measurement results based on the turntable system cannot truly reflect the magnetic levitation performance of the system under actual linear translation

Abstract

The invention discloses a device and a method for testing the linear translation dynamic performance of a high-temperature superconducting magnetic levitation system. The device comprises a base, a horizontal sliding table module, a vertical sliding table module, a three-axis force sensor, a low-temperature Dewar and a permanent magnet track, the horizontal sliding table module is arranged on the base, and the permanent magnet track is connected to the horizontal sliding table module and is driven by the horizontal sliding table module to do linear translation reciprocating motion; the low-temperature Dewar is arranged above the permanent magnet track, a high-temperature superconducting block is fixed at the bottom of the low-temperature Dewar, the top of the low-temperature Dewar is connected with the vertical sliding table module through the three-axis force sensor, and the vertical sliding table module drives the low-temperature Dewar to move vertically. According to the invention, through linear translation reciprocating motion, the continuous dynamic operation of the system is realized, and meanwhile, the problems of limited length of a permanent magnet track line and track curvature deviation caused by a circular permanent magnet track line are solved, so that a measurement result is closer to dynamic characteristics of the system under an actual operation condition.

Description

technical field [0001] The invention relates to the field of dynamic performance testing of a high-temperature superconducting maglev system, in particular to a linear translational dynamic performance testing device and a measuring method for a high-temperature superconducting maglev system. Background technique [0002] In the dynamic performance measurement of the high-temperature superconducting maglev system, due to the limitation of the length of the permanent magnet track and the site, the method of replacing the straight with a curved track is often used, and the circular permanent magnet track turntable is used instead of the linear permanent magnet track. The low-temperature Dewar is set above, and through the rotation of the turntable, the continuous dynamic operation of the low-temperature Dewar on the permanent magnet track is indirectly simulated. Since the circular permanent magnet track has a certain curvature, which is different from the actual permanent mag...
