Embodiment Construction

[0038] The present invention will be further elaborated below in conjunction with embodiment.

[0039] Such as Figure 1-11 As shown, the gravity unloading scheme of the present invention, by changing the installation adapters of the rotor assembly and the stator assembly, can realize the suspension of the outer casing part or the inner central axis part of the product under test, wherein the rotating part of the product under test must be the Suspended parts. The present invention is applied to the products whose outer shell parts are electrically connected. The scheme of suspending the outer shell parts requires more configurations than the scheme of suspending the internal central shaft parts. The specific implementation mode will now be described by taking the suspended outer shell parts as an example.

Abstract

The invention relates to a rotary joint ground gravity Lorentz force magnetic suspension unloading system which comprises a stator assembly, a rotor assembly, a conducting ring assembly and a conducting ring drive control circuit. The stator assembly comprises a fixed horizontal support, a stator installation switching support, a center shaft switching tool, a stator magnetic steel assembly of a parallel double-structure voice coil motor and a tested product center shaft component, and the stator installation switching support is fixedly installed on the fixed horizontal support. The stator magnetic steel assembly of the parallel double-structure voice coil motor and the tested product center shaft component are sequentially arranged on the center shaft switching tool; and the rotor assembly comprises a tested product outer shell part, a rotor installation adapter plate and a parallel double-structure voice coil motor rotor coil assembly. After constant current is applied to a rotor coil assembly of the parallel double-structure voice coil motor, electromagnetic force parallel to the axial direction is generated, and a rotary joint component fixedly connected to a rotor coil component is driven to float or descend.

Description

technical field [0001] The invention relates to a rotary joint ground gravity Lorentz force magnetic levitation unloading system, which belongs to the technical field of spacecraft ground tests. Background technique [0002] With the development of aerospace technology, the requirements for the performance of spacecraft mechanism products in orbit are getting higher and higher. The ultra-wide-coverage optical satellite currently being researched is an ultra-wide, high-resolution optical satellite for vertical-orbit scanning and along-track mosaic imaging. Research. The satellite is equipped with a high-resolution camera and a multi-function camera. The satellite can be divided structurally into two parts, the platform cabin and the load cabin. The rotary joint is installed in the platform cabin, and the load cabin is supported by magnetic levitation support. The high-precision magnetic levitation rotary joint is used as the support of the wide-format high-resolution camera...
