Description
Technical field
The present invention relates to the chassis structure guard technology field of MRAP, be specifically related to a kind of novel
The lightweight double V-shaped sandwich structure chassis of MRAP.
Background technology
Recently as day by day highlighting, for unshielded vehicle in conflict process of terrorism and regional conflict
With the improvised explosive devices of light-duty protection vehicle, especially equipped with the improvised explosive devices of explosive forming ammunition,
Have become as a kind of strategic arms of antagonism government military power.The states such as the U.S. and Britain are in Afghan and Irak army
Thing is on, has widely applied MRAP (MRAP).But, owing to this car is bulky,
Protective capacities and the poor problem of mobility the most increasingly cause concern.For MRAP,
In addition to power output, car body profile and armament systems, it is most important that be exactly MRAP chassis
Design.When MRAP is acted on by detonation wave, chassis can by one the biggest upwards
Instantaneous strong dynamic load, produces bigger deformation then, causes vehicle interior structure and member to need to bear very
Big initial peak value load, thus form the maximum injury to vehicle interior structure and member.At present, defense sector
The employing scheme of the chassis design of thunder immediate action drill car has at the bottom of single flat, monolayer shallow V, monolayer deep Vee hull and double
V-type.These designs play an important role to improving MRAP impact resistance, but
It is the increase in the weight of MRAP self, reduces its mobility.Accordingly, it would be desirable to anti-Rhizoma Anemones flaccidae
The chassis structure of immediate action drill car carries out innovative design, designs lightweight and has the chassis of excellent impact resistance
Structure, tackles Protean improvised explosive devices and the threat of blast formation and destruction, protects to greatest extent
Protect equipment and the safety of member in armored vehicle.
Summary of the invention
For the problem overcoming above-mentioned prior art to exist, it is an object of the invention to provide a kind of novel defense sector
The lightweight double V-shaped sandwich structure chassis of thunder immediate action drill car, this sandwich structure chassis can disperse that anti-Rhizoma Anemones flaccidae is counter to be lied prostrate
Hit the explosion wave in underbody portion, there is lightweight, rigidity is big, anti-impact force is strong, the advantage such as easily fabricated.
Realize dispersion bomb debris and explosion wave by the design of double V-shaped sandwich structure, reduce chassis change upwards
Shape amount, meets quick-fried simultaneously outside double V-shaped sandwich structure and designs distributed guiding gutter, it is achieved to bomb debris
With the rapid dispersion of explosion wave, reducing the impact immediately below base plate, the most distributed guiding gutter is all right
Increase the rigidity of double V-shaped structure, improve the impact resistance of structural chassis structure.
For reaching object above, the present invention adopts the following technical scheme that
The lightweight double V-shaped sandwich structure chassis of a kind of novel MRAP, including being welded on anti-Rhizoma Anemones flaccidae
The gradient porous metal foam of car body horizontal sandwich base plate 2 bottom immediate action drill car body 1, gold gradient porous with car body
Belong to the double V-shaped gradient porous metal foam sandwich structure 3 that foam levels sandwich base plate 2 two bottom sides is welded mutually,
Described meeting of double V-shaped gradient porous metal foam sandwich structure 3 is provided with guiding gutter 4 on quick-fried.
Described car body gradient porous metal foam sandwich base plate 2 and double V-shaped gradient porous metal foam sandwich knot
The upper and lower panel of structure 3 all uses armor, car body gradient porous metal foam sandwich base plate 2 and double V-shaped
The sandwich layer of gradient porous metal foam sandwich structure 3 uses gradient porous metal foam.
The density of described gradient porous metal foam is gradually increased from top to bottom.
Described car body gradient porous metal foam sandwich base plate 2 and double V-shaped gradient porous metal foam sandwich knot
The thickness of the upper and lower panel of structure 3 is identical or different.
Described guiding gutter 4 is the half-sine wave rib of array.
The most relatively, the present invention possesses following advantage:
When there is the attack from chassis, the shell configurations of double V-shaped structure is designed to effectively will upwards
Brisance be distributed to vehicular sideview, to greatest extent reduce shock in double V-shaped structure
The initial peak value load produced, reduces the chassis caused due to blast impulse deformation upwards, reduces personnel straight
The impact force action received, is a kind of effective Explosion-proof Design.MRAP chassis double V-shaped
The sandwich layer of sandwich structure uses lightweight, high specific strength, the gradient porous metal foam of high specific stiffness, Ji Nengbao
The rigidity of card body construction and intensity, can alleviate again car body weight, improves the motility of MRAP
And mobility.Realize broken to bomb by meeting quick-fried the distributed guiding gutter of design outside double V-shaped sandwich structure
Sheet and the guiding of explosion wave and rapid dispersion, reduce the shock time and reduce base plate just under
The impact of side, the most distributed guiding gutter can also increase the rigidity of double V-shaped structure, improve structure further
The impact resistance of chassis structure.
Accompanying drawing explanation
Accompanying drawing is the structural representation on the chassis of the present invention.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
