An explosion-proof structure of a variable-section gradient foam sandwich cylinder

Abstract

The invention discloses a variable-cross-section gradient foam core cylinder anti-explosion structure. The variable-cross-section gradient foam core cylinder anti-explosion structure aims at reducingthe mass of the anti-explosion structure and improving the anti-explosion performance of the structure. The variable-cross-section gradient foam core cylinder anti-explosion structure is overall cylindrical, and is composed of an inner surface plate, an inner core, a middle surface plate, a middle core an outer surface plate, an outer core, a shell, a bottom cover, a bottom core and a bottom surface plate. According to the variable-cross-section gradient foam core cylinder anti-explosion structure, variable-cross-section multilayer gradient foam core structural design is adopted, the containing volume of detonation products can be increased, and the total mass of the structure can be reduced. A gradient foam core can five full play to the excellent buffering and energy absorption performance of a gradient metal foam material, and the core structure has excellent mechanical properties of low mass, high strength, high energy absorption efficiency and the like. Compared with a traditionalcylinder anti-explosion structure of a single material, the explosion resisting performance is better and the total mass of the structure is lower.

Description

technical field [0001] The invention belongs to an explosion-proof structure, in particular to an explosion-proof structure of a variable cross-section multi-layer gradient foam sandwich cylinder. Background technique [0002] In recent years, terrorist activities around the world have become increasingly frequent, and terrorists are extremely rampant, seriously threatening the safety of public places such as squares, railway stations, and airports. In order to deal with explosives or suspicious explosives in a timely manner, public places such as stations and airports are generally equipped with explosion-proof tanks that can handle emergencies. Explosion-proof tank refers to the explosion protection structure that limits the explosion shock wave, fragments and detonation products inside the structure, and effectively protects the safety of personnel, equipment and the environment. The material of the explosion-proof tank shell of the common explosion-proof tank is general...
