Abstract
The utility model discloses a thunder anti - two V types of light of ambushing car in defense sector press from both sides core structure chassis, press from both sides the core bottom plate including welding in the anti - automobile body gradient porous metal foam level of ambushing bottom of the car body of defense sector thunder, the two V type gradient porous metal foams clamp core structures of both sides looks welded bottom the core bottom plate is pressed from both sides to automobile body gradient porous metal foam level, two V type gradient porous metal foams press from both sides meeting of core structure and are provided with the guiding gutter on the face of exploding, the vehicle side can be arrived with the dispersion of ascending brisance effectively to shell configuration design through two V type structures, and furthest's reduction explosion wave is used in the initial peak value load of two structural productions of V type, reduces and assaults the ascending deformation in chassis that causes owing to explode, reduces the impact force effect that personnel directly received, the quick dispersion to bomb piece and explosion wave is realized to guiding gutter through meeting the face of exploding outside two V types clamp core structure, reduces the operational time of explosion wave and the impact under the reduction bottom plate.
Description
Technical field
The utility model relates to the chassis structure guard technology field of MRAP, is specifically related to a kind of double V-shaped sandwich structure chassis of lightweight of MRAP.
Background technology
Day by day highlighting in recent years along with terrorism and regional conflict, for the improvised explosive devices of unshielded vehicle and light-duty protection vehicle in conflict process, the improvised explosive devices of explosive forming ammunition is especially housed, has become a kind of strategic arms of antagonism government military power.The states such as the U.S. and Britain, in Afghanistan and Irak military operation, have widely applied MRAP (MRAP).But because this car is bulky, protective capacities and the poor problem of mobility also more and more cause concern.For MRAP, except Power output, car body profile and armament systems, the most important thing is to be exactly the design on MRAP chassis.When MRAP is subject to the effect of detonation wave, chassis can be subject to a very large upwards instantaneous strong dynamic load, then larger distortion is produced, cause vehicle interior structure and member to need to bear very large initial peak value load, thus form the maximum injury to vehicle interior structure and member.At present, the employing scheme of the chassis design of MRAP have at the bottom of single flat, individual layer shallow V-shaped, individual layer deep Vee hull and double V-shaped.These designs play an important role to raising MRAP impact resistance, but are the increase in the weight of MRAP self, reduce its mobility.Therefore; need to carry out innovative design to the chassis structure of MRAP; design lightweight and there is the chassis structure of excellent impact resistance; tackle threat and the destruction of Protean improvised explosive devices and blast formation, protect the safety of equipment and member in armored vehicle to greatest extent.
Summary of the invention
In order to overcome above-mentioned prior art Problems existing, the purpose of this utility model is to provide a kind of lightweight of MRAP double V-shaped sandwich structure chassis, this sandwich structure chassis can disperse the explosion wave bottom MRAP, has lightweight, rigidity is large, anti-impact force is strong, is easy to the advantages such as manufacture.Dispersion bomb debris and explosion wave is realized by double V-shaped sandwich structure design, reduce chassis deflection upwards, outside double V-shaped sandwich structure, meet quick-fried the distributed guiding gutter of design simultaneously, realize the rapid dispersion to bomb debris and explosion wave, reduce the impact immediately below base plate, distributed guiding gutter can also increase the rigidity of double V-shaped structure simultaneously, improves the impact resistance of structural chassis structure.
For reaching above object, the utility model adopts following technical scheme:
A kind of double V-shaped sandwich structure chassis of lightweight of MRAP, comprise the horizontal sandwich base plate 2 of the gradient porous metal foam of car body be welded on bottom MRAP body 1, the double V-shaped gradient porous metal foam sandwich structure 3 of welding mutually with the gradient porous metal foam of car body horizontal sandwich base plate 2 two bottom sides, described meeting on quick-fried of double V-shaped gradient porous metal foam sandwich structure 3 is provided with guiding gutter 4.
The upper and lower panel of described car body gradient porous metal foam sandwich base plate 2 and double V-shaped gradient porous metal foam sandwich structure 3 all adopts armor, and the sandwich layer of car body gradient porous metal foam sandwich base plate 2 and double V-shaped gradient porous metal foam sandwich structure 3 adopts gradient porous metal foam.
The density of described gradient porous metal foam increases from top to bottom gradually.
The thickness of the upper and lower panel of described car body gradient porous metal foam sandwich base plate 2 and double V-shaped gradient porous metal foam sandwich structure 3 is identical or different.
Described guiding gutter 4 is the half-sine wave rib of array.
Compared to the prior art comparatively, the utility model possesses following advantage:
When there is the attack from chassis, brisance upwards can be distributed to vehicular sideview by the shell configurations design of double V-shaped structure effectively, reduce the initial peak value load that shock produces in double V-shaped structure to greatest extent, reduce the chassis distortion upwards because blast impulse causes, the impact force action that reduction personnel are directly subject to is a kind of effective Explosion-proof Design.The sandwich layer of the double V-shaped sandwich structure on MRAP chassis adopts the gradient porous metal foam of lightweight, high specific strength, high specific stiffness, the Rigidity and strength of body construction can be ensured, can car body weight be alleviated again, improve flexibility and the mobility of MRAP.Guiding to bomb debris and explosion wave and rapid dispersion is realized by meeting quick-fried the distributed guiding gutter of design outside double V-shaped sandwich structure, the impact reducing the shock time and reduce immediately below base plate, distributed guiding gutter can also increase the rigidity of double V-shaped structure simultaneously, improves the impact resistance of structural chassis structure further.
