Numerical Simulation of the Analogue Rules of the Kinetic Energy Projectile Vertically Penetrating Concrete Target

基于相似理论,文中分析了动能弹丸对混凝土进行侵彻的相似参数,建立了动能弹侵彻混凝土靶板的相似关系,选用不同模拟比的模型弹建立数值仿真模型,应用显式有限元程序LS-DYNA对所建立的模型进行了数值模拟。模拟结果表明模型弹和原型弹对混凝土的侵彻满足侵彻相似律。

In this paper, based on the analogue theory, the analogue parameters of the ball penetrating concrete target are analyzed, and the analogue rules of this penetration was established. Then. the models of the kinetic energy projectile penetrating the concrete with different simulation ratio were built, and the processes of the penetration were simulated by utilizing the program LS-DYNA. The simulation results are coincided with the theory analysis and the conclusion of some reference document. So, the penetration analogue rule is verified in this research.
