Abstract

The present application belongs to the technical field of suspension platform, and particularly relates to a multi-rigidity suspension platform based on magnetic field instability regulation, which realizes rigidity switching of the suspension platform through magnetic field instability regulation, avoids the problem that the rigidity of the traditional spring type suspension platform is fixed and cannot be quickly adjusted according to the bearing and vibration isolation requirements, and can be flexibly switched between low rigidity and high rigidity; only the magnetic field interaction between the magnetic control center component and the magnetic elastic plate is relied on to realize rigidity adjustment, without the need to be equipped with the complex driving device, sensing unit and real-time closed-loop control system required by the pneumatic and magnetic suspension system, so that the control difficulty and system complexity are reduced; only the base, the suspension platform, the guide element, the magnetic control center component and the instability magnetic elastic element are included, the number of movable parts is small, the assembly and use process are simple, the manufacturing cost and the post-maintenance difficulty are reduced while the rigidity adjustable capability is maintained, and the structural simplicity and the functional practicality are taken into account.
