Abstract

This invention refers to an active magnetic suspension axial performance tester, comprising a base component, a suspending plate component, a middle plate component, a sensor, a torquer. The base component is the four-pillar frame type structure. The suspending plate component is mounted in the frame by means of elastically suspending. The middle plate component is elastically supported on a base plate of the base component. The sensor and the torquer are mounted on a mounting bracket of the base plate of the base component. This magnetic suspension axial performance tester can realize the force measurement, with measuring precision of more than 0.5$%, can realize the shift measurement, with measuring precision of +(-) 0.001 mm. This invention can realize the measurement of the position signal voltage so as to realize the measurement of the axial magnetic suspension axial performance, such as the determination of the working capacitor C0, the measurement of the current quality factor Q and the measurement of the shift amount of the magnetic suspension three centers (geometric center, force center and signal center).

Description

technical field [0001] The invention belongs to the field of magnetic suspension axial performance testers, in particular to an active magnetic suspension axial performance tester capable of measuring force, displacement and position signal voltage. Background technique [0002] In inertial instruments, especially in liquid-floating inertial instruments, in order to reduce the frictional moment on the output shaft, improve the centering accuracy and improve the anti-interference ability of the instrument around the output shaft, it is necessary to use support centering technology to ensure that, commonly used Support centering methods include magnetic levitation and electric levitation. Magnetic levitation can not only eliminate the mechanical contact friction on the output shaft, improve the centering accuracy, but also provide the monitoring signal of the support system, accurately judge the actual working condition of the instrument, and has a simple structure, small size...
