Abstract
The invention provides a kind of vibration and noise reducing composite damping board, it is characterised in that including the most bonding metal level (1) and damping layer (2), the number of plies of metal level (1) and damping layer (2) is all higher than equal to two-layer.
Description
Technical field
The present invention relates to a kind of vibration and noise reducing material, particularly to the Constrained Plates that a kind of multiple structure is compound.
Background technology
Damping sheet is usually used in the vibration and noise reducing in the vehicles such as aircraft, boats and ships, automobile and the field such as lathe, building and processes.By damping sheet is pasted on the structure member of vibration, the vibrational energy of the structure that is stuck can be consumed, thus reduce its noise radiation.Damping sheet material is generally divided into free damping layer material peace treaty bundle damping sheet material.Damping layer material is usually and is made up of the high molecular polymer of rubber, asphaltic base, also known as visco-elastic damping material.Vector free axis method is directly to be pasted by visco-elastic damping material or be sprayed in the structure needing vibration damping or noise reduction, and appearance is without metal covering, when structural vibration (bending vibration), by the extension of viscoelastic material, absorbs vibrational energy.Restriction damping layer is that viscoelastic material is bonded in works, surface covers metal restriction plate, when structure occurs bending and deformation, except material stretches in addition to energy-absorbing as vector free axis method, between the damping layer and the metal restriction plate that are clipped in the middle by shear also can consumed energy, therefore restriction damping layer fissipation factor be more than vector free axis method.
For convenience of using, by the principle of restriction damping layer, viscoelastic material is combined with each other with sheet metal, forms Constrained Plates finished-product material.Directly Constrained Plates is pasted onto during use and needs to be formed in the structure of vibration damping restriction damping layer.Common Constrained Plates is double-decker, and its composition is that one layer of viscoelastic material adds layer of metal thin plate, the CY-1 type damping material produced such as Changzhou Lan Ling rubber plant.Such material weak point one is that fissipation factor is relatively low, and two is that temperature adaptation scope is narrower.
Summary of the invention
(1) goal of the invention
Instant invention overcomes deficiency of the prior art, it is provided that the damping sheet material that a kind of multiple structure is compound.
(2) technical scheme
A kind of vibration and noise reducing composite damping board, it is characterised in that including the most bonding metal level (1) and damping layer (2), the number of plies of metal level (1) and damping layer (2) is all higher than equal to two-layer.
Technique effect: use multiple structure, damping, the material of sheet metal, the number of plies, thickness can be carried out preferably by calculating and vibration test (mensuration fissipation factor) according to by frequency characteristic and the temperature environment of vibration-proof structure, thus realize designing as required the performance of damping sheet on the basis of current material；Multi-layer compound structure improves the fissipation factor of damping sheet, and effect of vibration and noise reduction is better than common damping sheet；Each layer uses different types of viscoelastic material (choosing the viscoelastic material adapted according to using temperature) to expand the temperature applicable range of damping sheet.
(3) beneficial effect
Compared with prior art, the invention has the beneficial effects as follows: the performance of damping sheet 1, can be designed on the basis of current material as required；2, improve the fissipation factor of damping sheet；3, the temperature adaptation scope of damping sheet is expanded.
Accompanying drawing explanation
Fig. 1 is four layers of composite damping board structural representation.
Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings:
A kind of vibration and noise reducing composite damping board, it is characterised in that including the most bonding metal level 1 and damping layer 2, the number of plies of metal level 1 and damping layer 2 is all higher than equal to two-layer.Metal level 1 typically can use thickness 0.4mm～0.8mm aluminium sheet, damping layer 2 typically can use thickness 0.5mm～1.0mm rubber-based viscoelastic material, the concrete material of each layer and thickness by vibration test preferably (mensuration fissipation factor) can use between each layer and have matter adhesive (such as 3M type viscosity glue) to paste.During use, composite damping board and by between vibration-proof structure use have matter adhesive (such as 3M type viscosity glue) to paste.
Technique effect: use composite layered structure, damping, the material of sheet metal, the number of plies, thickness can carry out preferably, can designing the performance of damping sheet on the basis of current material as required by calculating and testing according to by the frequency characteristic of vibration-proof structure, stiffness characteristics；Multi-layer compound structure improves the fissipation factor of damping sheet, and effect of vibration and noise reduction is good；Different types of viscoelastic material is used to expand the temperature applicable range of damping sheet by each layer.
