A Composite Rigidity Large Damping Vibration Isolator

Abstract

The invention belongs to the technology application field of vibration isolation buffering and relates to a composite-rigidity and large-damping vibration isolator. The composite-rigidity and large-damping vibration isolator comprises a lower U-shaped beam 1, an upper U-shaped beam 2, an upper connecting disc 3, a metal wire mesh spring 4, U-shaped beam connecting bolts 5, U-shaped beam connectingnuts and gaskets 6, a lower connecting disc 7, a connecting disc pre-tightening nut 8 and a connecting disc gasket 9. The rigidity of the vibration isolator is commonly provided by the upper U-shapedbeam, the lower U-shaped beam and the metal wire mesh spring, the damping is mainly provided by the metal wire mesh spring, the lateral rigidity and structural strength of the vibration isolator canbe greatly improved at the same time through the upper U-shaped beam and the lower U-shaped beam, and therefore the composite-rigidity and large-damping vibration isolator can have a long service lifeand high reliability.

Description

technical field [0001] The invention relates to the application field of vibration isolation and buffering technology, in particular to a damping vibration isolator with high composite stiffness. Background technique [0002] With the development of rail vehicles, aircraft, and ship technologies, the vibration environment on various vehicles will become increasingly complex, and the equipment carried on them will have increasingly stringent requirements on the vibration environment. Especially for electronic and optical equipment, in order to improve the measurement and control accuracy and increase the reliability of its work, it is necessary to install efficient vibration isolation and vibration reduction devices between the equipment and the carrier platform. [0003] Most of the current metal spring vibration isolators focus on the isolation of vertical vibration, and the lateral stiffness is insufficient. However, various mobile platforms will vibrate in at least six d...

AI Technical Summary

Problems solved by technology

This swinging condition can easily cause beam misalignment, making it difficult to meet the vibration isolation requirements of optoelectronic equipment

[0004] At present, the mainstream metal vibration isolators are mostly single stiffness and damping structure, the vibration isolation mechanism is single, the vibration isolation frequency has a lower limit, and the low frequency vibration isolation effect is poor

In a complex vibration environment, it is difficult to meet the stringent requirements for vibration control of precision electronics, optics and other equipment
