Problems solved by technology

[0004] At present, most of the protective armor in the explosion vessel is made of armor steel, but the method of simply using armor steel is not a good choice. First of all, its anti-penetration performance is not optimal. It is easy to hurt people in the process

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] as attached figure 1 As shown, the protective armor structure in the explosion vessel is composed of deformed magnesium alloy 2, aluminum oxide ceramic 3, anti-explosion coating 4 and aluminum foam 5. The inner armor structure is closely attached to the main load-bearing layer of the explosion vessel through beading.

[0027] The design method of the protective armor structure in the explosion vessel, first fix the deformed magnesium alloy 2 with a thickness of 2 cm on the inner side of the main load-bearing layer 1 of the explosion vessel, and then bond the aluminum oxide ceramic 3 to the deformed magnesium alloy 2 with epoxy resin On the bullet-resisting surface of the alumina ceramic 2, a 2 mm thick LINE-X anti-knock coating 4 is sprayed, and a layer of 5 cm thick aluminum foam 5 is placed outside the anti-knock coating 4 .

Abstract

The invention discloses a design method of an explosion vessel inner protective armor structure. The design method comprises the following steps of determining the thickness of the explosion vessel inner protective armor structure according to the fragment quality and speed generated by an explosive when an explosion vessel is used; arranging a layer of wrought magnesium alloy on the inner side ofa main body force bearing layer of the explosion vessel firstly; adhering a layer of aluminum oxide ceramics to the inner side of the wrought magnesium alloy with epoxy resin; spraying the inner sidesurface of the aluminum oxide ceramics with an LINE-X explosive-proof coating as a crack preventing layer; and putting a layer of foamed aluminum clinging to the aluminum oxide ceramic explosive-proof coating to be used for attenuating the energy of air shock waves and lowering the fragment group speed. The inner protective armor structure is tightly fitted to the main body force bearing layer ofthe explosion vessel together through a pressing strip. The invention also discloses the explosion vessel inner protective armor structure. The explosion vessel inner protective armor structure provided by the invention is high in protection coefficient, good in anti-bullet effect, light in structure and convenient to change.

Description

technical field [0001] The invention relates to a protective structure of an explosion container and a design method thereof, in particular to a protective armor structure in an explosion container and a design method thereof. Background technique [0002] Explosion vessels can shield and isolate explosion shock waves, limit the range of detonation products and fragments, and effectively protect the safety of personnel, equipment, and the environment. Therefore, they are widely used in the fields of national defense, industry, scientific research, and public safety. In national defense and military affairs, explosive containers are important experimental sites for weapon research, and are used to store and transport weapons and ammunition; in industrial production, explosive containers can provide safe processing places for production processes such as explosive welding; in scientific research, The explosion process can be studied safely and conveniently in the explosion ves...
