Problems solved by technology

In the actual use of the compression dynamic shock absorber, the long-term inertial effect of the mass block makes the rubber prone to ultra-limit deformation, tearing or aging, and damage occurs, reducing the use function and life, and the mass block is easy to fall off, which is not conducive to safety assurance
The rubber stiffness of the compression structure is relatively high, and there are great limitations in the application of low-frequency vibration control

Abstract

The invention relates to an attached mounting type miniature compound dynamic vibration absorber and belongs to the technical field of noise vibration control. The attached mounting type miniature compound dynamic vibration absorber comprises an elastic base, assembling supports, elastic films, a mass block and connecting pieces for assembly of the compound dynamic vibration absorber. The elastic base and the two assembling supports form a body of the compound dynamic vibration absorber. The elastic base is of a rubber type cylinder structure. The two assembling supports are arranged and are each of a metal-pipe-shaped structure with a certain height. One of the assembling supports is connected with the elastic base through the connecting pieces. The elastic films and the mass block form vibration absorbing elements of the dynamic vibration absorber, the two vibration absorbing elements are arranged, one of the vibration absorbing elements is located between the two assembling supports and is connected with the two assembling supports through the elastic films, and the other vibration absorbing element is located at the top end of the dynamic vibration absorber and is connected with the assembling supports through the connecting pieces. By the adoption of the attached mounting type miniature compound dynamic vibration absorber, the low frequency and broadband vibration suppression and noise reduction can be achieved, and the vibration suppression and noise reduction performance can be further enhanced when mounting dynamic vibration absorbers are distributed periodically.

Description

technical field [0001] The invention belongs to the technical field of noise and vibration control. The invention relates to a miniature compound dynamic shock absorber which can be attached and installed. Background technique [0002] Harmful vibration can cause premature damage to products and structures, reduce service life, and even endanger people's health and safety. Therefore, harmful vibration must be reduced or eliminated as much as possible. In engineering, there are many ways to reduce or eliminate vibration, such as eliminating or weakening vibration source, isolating or attenuating vibration transmission, dynamic vibration absorption, increasing damping, adjusting structure, etc. Among them, dynamic vibration absorption is a passive vibration reduction technology, which is a relatively economical and effective method, and is widely used in industries such as automobiles, engineering machinery, construction, ships, and aviation. [0003] Dynamic vibration abso...
