Self-driven rotation shaft vibration and local position stabilization system

Abstract

The invention provides a self-driven rotation shaft vibration and local position stabilization system, which comprises a space vibration stabilization device. The space vibration stabilization device comprises a load disc, a repulsion drive electromagnetic device, a transfer entity, a permanent magnet isolation disc and a transfer shell, wherein the transfer entity matched with the transfer shell is arranged on the load disc; the repulsion drive electromagnetic device arranged on the load disc and the permanent magnet isolation disc arranged on the transfer shell interact mutually to form a repulsion magnetic circuit; when the repulsion drive electromagnetic device does not work, the load disc is separably supported on the transfer shell via the transfer entity; and when the repulsion drive electromagnetic device works, repulsion generated by the repulsion drive electromagnetic device relative to the permanent magnet isolation disc drives the transfer entity to be away from the transfer shell so as to drive the load disc to be separated from supporting of the transfer shell. The system can carry out response driving control on space displacement and space vibration effectively, and a target vibration isolator can be kept stable.

Description

technical field [0001] The invention relates to the field of drive technology, intelligent drive control technology, electromagnetic permanent magnet direct drive and precise control of rotational position, in particular, to a vibration and local position stabilization system of a self-driven rotating shaft. Background technique [0002] The precision controllable rotation drive device is mainly used in the adjustment of the spatial position of the mechanism, the tracking of the target object, and the active control of the vibration of the flexible structure. By controlling the rotation of the sub-components, the adjustment of the spatial position of the mechanism is realized, and then the tracking of the target object and the active control of the vibration of the flexible structure are realized.

AI Technical Summary

Problems solved by technology

The existing rotary drive device is mainly a rotary motor. This kind of mechanism itself has a relatively complicated structure, and often needs to be combined with other transmission components to control the motion. The efficiency is low and the response speed is slow.

In particular, in the case of limited volume, it is often unable to provide a large driving torque, and cannot meet the needs of modern industry for micro precision drive control and positioning
