Description
Technical field
The present invention relates to shock resistance field, specially a kind of shrinkage pool honeycomb cavity structure anti-impact coating.
Background technology
Naval vessel has turned into the main composition of various countries' military developments as important marine fighting capacity, with modern weapons science and technology
Development, higher requirement is proposed to the impact resistance on naval vessel.Shock wave caused by the underwater untouchable blast such as torpedo
As most common destruction source, how effectively to prevent that it is particularly significant to injuring for naval vessel.With negative poisson's ratio characteristic
Shrinkage pool honeycomb and it has been widely used in the advantages that its outstanding mechanical property and inter-cell micro-structural designability
The technical fields such as Aero-Space, marine ship, railway traffic are as buffering, energy-absorbing material.
Anti-impact coating is typically containing the structures such as example spherical, cylindrical cavity of various cavity structures, this kind of anti-impact covering
Layer has other such as impact resistances, protection hull anti-seawater corrosion performance concurrently mainly to absorb shock wave.Horizontally arranged shrinkage pool
Honeycomb anti-impact coating has the characteristics that preferable shock resistance and impact resistance, under the conditions of improving underwater structure to temporary impact
Security performance.Compared with traditional spherical, cylindrical coating, horizontally arranged shrinkage pool honeycomb cavity coating also has negative pool
Pine is more beneficial for integrally-built stability protection than effect.
The content of the invention
It is an object of the invention to provide a kind of horizontally arranged shrinkage pool honeycomb cavity structure anti-impact coating, can effectively carry
High impact resistance, and also have impact resistant capability concurrently, the impact that can effectively reduce submerged structure is injured, to improving underwater knot
The impact resistance of structure plays an important role, with overcome the deficiencies in the prior art.
To achieve the above object, the present invention provides following technical scheme：A kind of shrinkage pool honeycomb cavity structure anti-impact coating,
Including panel layer, the shrinkage pool honeycomb cavity arranged with periodicity level is set, panel layer is aluminium sheet or steel plate and should in panel layer
The center line of shrinkage pool honeycomb cavity and shock wave or elastic wave propagation direction are perpendicular.
Preferably, the section of the shrinkage pool honeycomb cavity structure anti-impact coating is any in following three kinds of spread patterns
It is a kind of：
（a）The cell element angle of flare of all shrinkage pool honeycomb cavitys is all identical；
（b）The cell element angle of flare of every layer of shrinkage pool honeycomb cavity is identical, the cell element angle of flare of the shrinkage pool honeycomb cavity between different layers
It is in be gradually reduced along stress wave propagation direction；
（c）The area of section of every layer of honeycomb cavity is identical, and the section face of adjacent two row honeycomb cavity changes in cycle staggering.
Shock wave resistance of the present invention or impact resistance mechanism are summarized as follows：
（1）Due to there is substantial amounts of shrinkage pool honeycomb cavity in coating, shrinkage pool honeycomb has negative poisson's ratio characteristic, when coating is by edge
When a direction is compressed, perpendicular direction expands up and down,；
（2）Shock motion is to the corner of shrinkage pool honeycomb cavity structure, because the discontinuity of structure causes stress wave to produce
Waveform changes（Fig. 4）, the change of continuous waveform adds their propagation paths in coating, and this means that consumption is more
Stress wave energy；
（3）Air impedance is far smaller than the impedance of coating panel and aqueous medium, changes the impedance between hull and aqueous medium
Characteristic, shock wave is set largely to be dissipated in the air in coating.
Due to comprising shrinkage pool honeycomb cavity structure in the present invention, from macroscopically, being the group velocity that changes coating（Energy
Measure spread speed）And equivalent elastic modulus, these changes and structural parameters（Honeycomb cavity unit wall thickness, cell element angle of flare etc.）With
The material parameter of aluminium sheet or steel plate in itself is relevant, and determines the impact resistance of coating.
It is an advantage of the invention that flexible design, can design the covering of different-thickness and the different cell element angles of flare as requested
Layer.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Figure is referred to, the present invention provides a kind of technical scheme：A kind of shrinkage pool honeycomb cavity structure anti-impact coating, including face
Flaggy 1, panel layer 1 is interior to set the shrinkage pool honeycomb cavity 2 arranged with periodicity level, and panel layer 1 includes aluminium sheet and the shrinkage pool honeybee
