弹丸转速对PELE侵彻钢筋混凝土靶横向效应的影响
Effect of Projectile Rotation Rate on Lateral Effect of PELE Penetrating Reinforced Concrete Target
摘要
Abstract
To study the effect of projectile rotation rate on the lateral effect of penetrator with enhanced lateral effects (PELE)penetrating reinforced concrete target, the numerical simulation of PELE penetrating reinforced concrete target with different rotation rates was performed under the condition of three impact target velocities of 600,700 and 800m/s,and the simulation model under the conditions of different impact target was verified by testing method.The results show that the error of opening size between the simulation results and the experimental ones is less than 5%, showing that the simulation model can accurately simulate the process of PELE penetrating reinforced concrete target.With increasing the rotation rate, more rotation rate kinetic energy lost translates into the energy that used to break the reinforced concrete target and make the opening size of reinforced concrete target increase.Under the same impact target velocity, opening size is improved by (8±2)% when the rotation rate increases from 10000r/min to 25000r/min.Therefore, increasing projectile rotation rate is beneficial to improve the opening size of the PELE penetrating reinforced concrete target.关键词
