Abstract

The invention discloses a spring vibration isolator coupled with electromagnetic damping, which comprises a spring vibration isolation unit, the spring vibration isolation unit comprises a load platform, a spring and a base from top to bottom, and the spring vibration isolator further comprises a horizontal magnetic field generation unit arranged outside the spring, the electromagnetic damping generation unit is arranged between the horizontal magnetic field generation unit and the spring and is suspended below the load platform in an insulating manner; the horizontal magnetic field generation unit is a magnetic material array, and the electromagnetic damping generation unit comprises a conductor plate and magnetic material rods vertically arranged on the conductor plate at intervals. The problems of friction, liquid leakage and the like do not exist in electromagnetic damping, and the vibration isolation performance is excellent.

Description

technical field [0001] The invention relates to the technical field of environmental vibration and noise control, in particular to a spring vibration isolator coupled with electromagnetic damping. Background technique [0002] Equipment vibration will cause equipment wear and reduce the service life of equipment. At the same time, vibration is transmitted through solids such as rigid connectors, ground or buildings, which will generate vibration and secondary radiation noise pollution. In order to reduce vibration pollution, a vibration isolator is usually installed at the bottom of the equipment to isolate the vibration of the equipment. Spring vibration isolators are widely used in the field of equipment vibration isolation because of their low natural frequency, high stiffness, and strong load capacity. [0003] For example, a spring vibration isolator is disclosed in the patent specification whose notification number is CN212985909U. The spring vibration isolator is arr...
