Research On The Performance Of Series-in-flight Warhead Penetrating Reinforced Concrete

This article describes the power performance of a tandem attacking warhead penetrating reinforced concrete,The use of shaped charge penetrating the open hole,and after the penetration of the blasting killing program.The use of theoretical analysis,simulation calculations,experimental verification combined research methods,Systemically studied the mechanism and design method of the tandem combat division.The main content of this article:First,it introduced the classification and characteristics of anti-hard target warheads,and stated the history of the development of warheads at home and abroad.Now and its future.Explained the significance of the research of the warhead.starting from the theory of classical shaped charge jet,the theory of shaped jet is introduced,The relationship between jet and penetration depth and aperture was analyzed.the design process of the front-end shaped charges was introduced,and the factors that influence the power of the jet were analyzed.Using Ture Grid,LS-DYNA and other simulation software to simulate and contrast the jet formation and penetration process of the front-stage shaped charge of different drug mask structures.Choose a drug mask structure that guarantees both penetration and depth.Next,the performance characteristics of the new titanium alloy drug mask material were introduced,and the simulation software was used to compare the formation of the jet of titanium,copper,andaluminum alloy material.Penetrate the process of reinforced concrete.Combined with tests,it is believed that the unique toughness characteristics of the titanium alloy medicane shield provide a good choice for the development of high-performance offensive warheads,and has a wide range of application prospects.based on the LS-DYNA simulation software,the influence of the detonation wave on the follow-through charge at the rear stage is studied.Analyzes the pressure between different front and rear stage spacings and different head structures with front-entry detonation waves on the rear-stage charge with charge,With the loss of kinetic energy into the bomb and the impact of the missile body deformation.A reasonable spacing between the front and back levels has been determined.Finally,the structure of the overall series warhead bullet was first determined,and the rationality of the structure was verified by experiments,In Chapter 5,the structure of the overall series attacking bullet was first determined,and the rationality of the structure was verified by experiments,With the advancing of the incoming missile,it further validated the penetration of the front-end shaped charge,With the advancing of the incoming missile,it further validated the penetration of the front-end shaped charge.
