Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention is provided.
The invention provides a flat plate opposite-opening type single-machine shelter garage protection door 6, which adopts the interlayer combination of armor steel and composite materials, and the protection door sequentially comprises the following structures from an explosion-facing surface to the interior of a cave garage: the protective door comprises a protective door panel 1, a gap supporting frame 2, a PE energy absorption layer 3, an energy absorption buffer layer 4 and an armored steel backboard 5; the protective door 6 is arranged outside the cave depot 8 through a door frame 7.
The protective door panel 1 is made of 10-20mm6211 armor steel, a 15-25mm gap is formed between the protective door panel 1 and the PE energy absorption layer 3 and is supported by a gap supporting frame 2, the PE energy absorption layer is made of 15-25mm UHMWPE film composite plates, the energy absorption buffer layer is made of 20-30mm honeycomb aluminum structures, and the armor steel backboard is made of 5-15mm616mm armor steel as shown in figure 1. The anti-explosion door can effectively resist the damage of fragments and shock waves caused by the explosion of 1000-pound MK83 which is 5m away from the door, and protect the safety of airplanes, equipment and personnel in the cave.
And a gap of 20mm is designed between the first layer explosion-facing surface and the composite material layer, and the purpose of protection is achieved by utilizing the gap effect. Firstly, the method comprises the following steps: the stress wave is blocked and propagates to the backside when the first layer of armor steel is impacted at high velocity and generates a stress wave in its interior. Total reflection occurs at the interface of the back of the armor steel and the air. This reduces the transmission of stress waves to the second composite layer, which is not exposed to the stress waves. And secondly, in the gap structure, when the armor steel is acted by external mechanical force, force transmission is generated inside, but when the armor steel is on the back surface, the mechanical force cannot be transmitted to the second layer of composite plate due to air obstruction, so that the armor steel is not acted by the external force. Thirdly, the method comprises the following steps: pressure relief, when impacted, the inside of the armor is subjected to huge pressure, and the gap becomes a good buffer layer and a pressure relief space due to the great compressibility of air. Fourthly: the free motion space of the beating object, in the large gap structure, when the horizontal distance of the gap is larger than the length of the solid beating object, the beating object can move freely in the gap, and the flight attitude of the beating object is unstable, so that the penetration capacity of the beating object is reduced. Fifth, the method comprises the following steps: and preventing the crack from expanding, wherein in the gap structure, when the first layer of armor steel cracks, the crack cannot be transmitted to the second armor plate due to the existence of the interface, and the expansion is stopped.
A second layer of 20mm PE composite board and a 24mm energy absorption buffer layer (honeycomb aluminum) are designed and mainly responsible for absorbing residual shock waves and intercepting high-speed fragments, and the characteristics of high attenuation and light weight, high energy absorption efficiency and high transmission speed of strain waves of the explosion shock waves are utilized.
And designing a third layer of 10mm616mm armor steel to be responsible for high-strength support of the second energy-absorbing buffering layer and interception of high-speed fragments.
The invention adopts the interlayer combination of armor steel and composite material, and the structure of a protective door plate from an explosion-facing surface to the interior of a cave depot is as follows: 15mm6211 armor steel +200mm clearance +20mm UHMWPE membrane composite plate +24mm energy absorption buffer layer +10mm616mm armor steel, and the clearance support frame adopts a 200mm rectangular steel frame.
The light high-resistance composite material protective door adopts the interlayer material mechanism clearance effect, greatly lightens the weight of the door plate of the protective door on the premise of ensuring the protection, and shortens the opening time of the protective door.
The cave depot protection door is used as a first barrier for cave depot protection, is a part which is stricken by enemy and is easy to damage, and the whole protection efficiency of the cave depot is directly influenced by the degree of function exertion.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
