Title:
ELECTRIC MAGNETIC-LEVITATION MAGNET VIBRATION AND IMPACT TEST APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/050991
Kind Code:
A1
Abstract:
An electric magnetic-levitation magnet vibration and impact test apparatus, comprising a vibration table (100), an electromagnetic excitation mechanism (200), a hoisting mechanism (400), and a magnet mounting mechanism (300), wherein the magnet mounting mechanism (300) is used for mounting a magnet (500) to be tested, the hoisting mechanism (400) is used for hoisting said magnet (500) to a preset position, the magnet mounting mechanism (300) is arranged on the vibration table (100), said magnet (500) and the electromagnetic excitation mechanism (200) are arranged opposite each other, and electromagnetic induction can be produced between said magnet (500) and the electromagnetic excitation mechanism (200) so as to levitate said magnet (500); the internal temperature of said magnet (500) can be adjusted, and the current of the electromagnetic excitation mechanism (200) can be adjusted; and when said magnet (500) is in a walking wheel walking state of a magnetic levitation vehicle, a state of levitation of the magnetic levitation vehicle, and a magnet quenching state when the magnetic levitation vehicle is levitated, the vibration table (100) can provide vibrations for said magnet (500), such that vibration and impact test simulation for said magnet (500) in the three states is realized. The apparatus can test the dynamic environment adaptability of a magnet subjected to vibrations and impact.
