Magnetic suspension active vibration isolator and vibration isolation method

Abstract

The invention discloses a magnetic suspension active vibration isolator and a vibration isolation method, in which the vibration isolation equipment is supported by a support, and the support is supported by a base; both the support and the base are provided with a magnetic device and a disturbance collector , the magnetic levitation state can be formed between the support and the base through the magnetic device, and the disturbance force of the equipment and the ground can be obtained respectively through the disturbance collectors of the support and the base; and the magnetic devices of the support and the base are connected to the control system, according to The acquired disturbance signal makes it possible to correct the disturbance while forming a magnetic levitation state between the support member and the base, so as to achieve the purpose of vibration isolation. The maglev active vibration isolator can separately collect the vibration disturbance signals of the equipment and the ground, and feed them back to the control system in time, so that the maglev active The vibration disturbance of the equipment can realize the stability of the equipment and ensure the precise operation of the equipment and the life of the equipment.

Description

technical field [0001] The invention belongs to the technical field of vibration isolators, and in particular relates to a magnetic suspension active vibration isolator and a vibration isolation method applied to high-end equipment and instruments. Background technique [0002] In recent years, the problem of vibration control has attracted more and more people's attention. According to different vibration control methods, vibration reduction technology can be divided into vibration isolation, vibration absorption, vibration elimination and vibration resistance. Vibration isolation is to take certain measures between the vibration source and the system, and install appropriate vibration isolation devices to reduce the vibration intensity transmitted to the vibration reduction target point. [0003] According to whether energy is needed, vibration isolation can be divided into passive vibration isolation and active vibration isolation. The former is also called passive vibrat...

AI Technical Summary

Problems solved by technology

However, it is still passive vibration isolation, not active vibration isolation. The vibration isolation of solid-borne sound has a certain lag, and it cannot effectively eliminate the vibration effect of the equipment itself. Further improvement is still needed.
