| With the development of modern defense systems,military command centers,arsenals,hangars,missile silos and other important mi litary facilities in many countries are built in strong protection of underground fortifications,bombs on the target incapable of action.In order to more effectively combat and damage this type of military targets,the world's military powers are vigorou sly strengthen the penetration of the ground penetrating weapons,the development of.On the one hand,the weapon target internal personnel,facilities and equipment to implement effectively combat,destroy the effective strength;on the other hand can gre atly damage the target solid protective layer,the protective layer to protect the target loss ability.In this paper,the design method and basis of XX kg grade A product are expounded,the main target of XX kg class A product is determined,and the desig n of warhead is put forward for the specific target analysis.Through the shock wave overpressure and environmental conditions,The design of the mechanical interface,the use of LS-DYNA and other finite element software for numerical simulation,accurate description of the material to simulate the penetration of the state function,designed to penetrate the warhead structure strength fully meet the penetration X Requirements for semi-infinite reinforced concrete targets.According to the research on the penetration of reinforced concrete and the ground test of XX kg grade A product,the product structure strength test,penetration test,corner test,drop test,charge stability test,power test according to the design requirements of a comprehensive analysis summary,the results show that the warhead is fully equipped to meet the ability to combat hard targets.In summary,through the above simulation and ground test,XX kg A products through research and testing can achieve the performance requirements;Th ey can achieve better performance,strike hard target of enemy military facilities. |
