Simulation Study Of Infrasound Shells Role In The Process Of Protection

The core objective in this paper is the problem of the processing of infra-soundweapon, using technique of theory analysis and numerical simulation to analyze andcalculate.The main Contents in this paper are as follows:1) Studied the theory analysis of infrasonic weapon system. Mathematical model ofpiston vibration was set up, using computational analysis. With the help of computer,work out the computer program to this model, that can calculate running results such asinfrasonic frequency and infra-sound radiation under different initial condition, such asinitial velocity.2) Studied the numerical simulation of the process of transmission of infrasonicweapon. A systematical analysis and discussion about the transmission of two kind ofpiston, with the help of the finite element software, some valuable calculating examplesand useful conclusion were got.3) Studied the numerical simulation of target district response of infrasonic weapon.A numerical analysis and discussion about a new kind of powerful infrasonic weapon werecarried out with the assistant of the finite element software. As the research of theinfrasonic is undergoing, people who work near the experiment field need to be protectedfrom the influence of infrasonic. The system design of protection and choose of protectioninstrument are also included in the paper.The research results indicate that using theory analysis and numerical simulationmethod to study the problem of kinetic projectile penetrating concrete target is feasible,and reaches better precision. The results can offer reference for further research andengineering calculation.
