Magneto-rheological vibration isolation bearing based on hybrid mode

Abstract

The invention relates to a magneto-rheological vibration isolation support based on a mixed mode. The support comprises a supporting rod, a base and an exciting coil, wherein the supporting rod is connected with a device subjected to vibration isolation, the base is connected with a vibration source, and the exciting coil is used for generating a magnetic field. Magneto-rheological cement gum are arranged between the supporting rod and the base and sealed in an elastic bag sleeve. The upper end and the lower end of the elastic bag sleeve are fixedly connected to the supporting rod and the base respectively. The base is fixedly provided with an outer sleeve. The supporting rod is located in an inner cavity of the outer sleeve. The upper end of the supporting rod extends out of the outer sleeve. The magneto-rheological elastomers are fixedly disposed between the supporting rod and the outer sleeve. The magneto-rheological vibration isolation support can adjust the magnetic field intensity of the vibration isolation support in real time according to outside vibration interference, vibration excitation is effectively tracked and responded, and vibration interference is effectively isolated within the wide-frequency range.

Description

technical field

[0001] The invention belongs to the technical field of vibration isolation, and relates to a magnetorheological vibration isolation support based on a mixed mode. Background technique

[0002] Vibration is ubiquitous in production and life, and mechanical vibration is usually harmful to engineering structures, mechanical equipment, and instruments. For instruments and equipment: on the one hand, mechanical vibration will loosen the fasteners in the test instrument and destroy its normal work; on the other hand, vibration will easily cause the instrument to vibrate, resulting in large measurement errors; Working in a vibrating environment can easily cause mechanical fatigue and even damage. Therefore, certain measures need to be taken to reduce the impact of harmful vibrations. It is a common practice to reduce vibration hazards by connecting a vibration isolation device in series between the vibration source and the vibration-isolated device to reduce the r...
