At present, the domestic and foreign explosive multiple terrorist attacks, terrorist attacks harm explosives is more and more big, at the same time for the explosives disposal work becomes more and more difficult, explosives disposal equipment equipment system, how to develop practical combat skills is very necessary. In accordance with the general steps of suspected explosives disposal, disposal equipment can be divided into detection equipment, emergency equipment, transportation equipment, explosion-proof equipment destroyed four categories, according to the actual situation at the scene, each kind of equipment and a variety of segments, in the whole process of disposal, and explosion-proof storage is very important.Explosion-proof storage equipment at home and abroad according to the tactical and technical index can be divided into closed spherical storage equipment and barrel storage equipment two categories, these two types of explosion-proof equipment, tube type storage equipment due to the use of non closed cylinder type structure and detonated explosives in the explosion-proof cylinder, a considerable influence on the external explosion the environment still has, on the other hand, the explosive blast in the internal wave for cylindrical structure is very uneven, the cylinder wall is easy to produce weak area, resulting in broken tube explosion. The explosion-proof ball adopts a hollow spherical structure closed, greatly reducing the explosives in the explosion tube explosion brings risks, to compensate for the lack of explosion-proof tube. But because the market of the existing explosion-proof ball size, open ball weight is too large, explosion-proof explosion-proof ball antiknock TNT equivalent is small, so there is an urgent need to develop larger ball size, ball proof open large antiknock and lightweight TNT equivalent, to cope with the increasingly serious security requirements.According to the design targets and requirements of parameters of explosion-proof ball optimization, two kinds of explosion-proof ball feasible overall design, described the design principle design scheme. The establishment of three-dimensional model of two kinds of explosion-proof ball structure.Because the ball is a core component of explosion-proof explosion-proof ball, is based on the whole weight design and equivalent antiknock performance, so the explosion-proof ball explosion simulation necessary simulation is very necessary, the structure of the explosion-proof ball antiknock performance and wall thickness parameter simulation for structural optimization. Through the simulation analysis, the optimal design can be explosion-proof ball structure selection, using different materials of special steel get maximum minimum wall antiknock TNT equivalent fixed sphere wall thickness and the fixed TNT equivalent case explosion-proof ball ball thick.Even if the explosion ball after the structure simulation and optimization of structure design and advanced science, to the reality in the process of production and processing are still subject to the processing capacity, should use field explosion test to detect the anti explosion performance to ensure the production of products with explosion-proof safety effectively.
