Problems solved by technology

[0003] Due to structural limitations, the load-carrying capacity of the existing wire mesh isolator is only tens of kilograms, and its natural frequency is greater than 10Hz, which cannot meet the installation and application requirements of some low-frequency (5Hz) environments and large-load (ton-level load) equipment.

Abstract

The invention discloses a vibration isolator. The vibration isolator comprises a base, a sealing cover, a mandrel, a cylindrical spring, a first metal wire net pad and a second metal wire net pad, wherein the sealing cover covers the base to form a cavity; the mandrel is arranged in the cavity for dividing the cavity into a first cavity body and a second cavity body; the first metal wire net pad sleeves the mandrel, and is arranged in the first cavity body; the second metal wire net pad sleeves the mandrel, and is arranged in the second cavitybody; the cylindrical spring sleeves the second metal wire net pad, and is arranged in the first cavitybody; one end of the cylindrical spring butts against the sealing cover, and the other end butts against the base; and the end, far awayfrom the base, of the mandrel is used for being connected with vibration isolated equipment. The vibration isolator forms an elastic buffer vibration isolation structure through a mode of combining the cylindrical springwith the first metal wire net pad and the second metal wire net pad, so that the needed bearing capacity is achieved, and the low-frequency damping purpose can be achieved.

Description

technical field [0001] The invention relates to the technical field of vibration isolation, in particular to a vibration isolator. Background technique [0002] With the increase of the operating speed of aircraft, vehicles and other vehicles, the magnitude of its knot vibration is getting larger and larger. In order to improve the comfort of the cabin and cabin environment, as well as the control accuracy of precision instruments and equipment installed on aircraft vehicles, Vibration isolation installations are required for airborne equipment, compartment floors, and precision instruments. [0003] Due to structural limitations, the load-carrying capacity of existing wire mesh isolators is only tens of kilograms, and its natural frequency is greater than 10 Hz, which cannot meet the installation and application requirements of some low-frequency (5 Hz) environments and large-load (ton-level load) equipment. In order to meet the installation problems of some low-frequency ...
