Slow with noise immune decay, penetration power is strong, it is difficult to it is implemented to hinder and controlled, seriously constrains the performance of these equipment performances
And riding comfort, or even directly influence equipment operation and the health and life security of passenger.
In Practical Project, often low-frequency vibration and noise are reduced using sound insulating material and damping material.It is but traditional
When isolating sound wave and vibration, the thickness and wave length of sound that generally require sound insulating material part match sound insulating material, example
Such as, if to isolate below 100Hz sound wave, it is necessary to which thickness exceedes 1m sound insulating material, and this is in automobile, train, aircraft etc.
In the compact equipment in inner space, it is clear that be unpractical；Although damping material has certain abatement to low-frequency vibration and noise
Effect, but with the continuous enhancing of the requirements such as lightweight, economy, the quality limitation to damping material is also increasingly stricter, passes
System damping material can not meet the needs of low frequency vibration damping noise reduction；Therefore there is an urgent need to develop new low frequency vibration damping acoustic damping materials.
In recent years, USN's development test institute, European information society technology research committee, China national nature fund
Supported energetically Deng to the theory of acoustic metamaterial and application study.Acoustic metamaterial refers to there is negative equivalent mass density
Or the artificial sub-wavelength structure of negative concrete moduli, 2000, common phonon crystal bandgap frequency was reduced two by Liu Zhengyou etc.
The individual order of magnitude, the limit value of Bragg diffraction is breached, realize the purpose that small size controls big wavelength, this is that low frequency research is opened up
New road and method.They realize equivalent negative mass density by introducing local resonance unit at low frequency.At low frequency,
Motion off resonance phenomenon just occurs, simultaneously because movement of pendulum can absorb the energy that sound wave is transmitted and taboo is produced at low frequency
Band.Therefore, low-frequency vibration is isolated with noise, acoustic metamaterial is a kind of extraordinary selection.
In summary, it is the low frequency vibration isolation problem of frequency range within 200Hz particularly below for 1000Hz, existing damping sheet,
Do not reach low frequency subtract, the requirement of vibration isolation；Structure is excessively heavy, and steric requirements or cost do not allow；Only to list
One frequency or narrower frequency band are effective；Therefore, it is a kind of have broadband, meet low frequency subtract, the New Damping plate of vibration isolation requirement
