【摘要】 随着混凝土目标的大量涌现,弹体对混凝土靶的侵彻得到越来越多的研究和关注。运用理论分析和数值仿真相结合的方法,分析讨论PELE和动能弹以一定的初始速率垂直侵彻混凝土靶的动态过程,并将二者进行比较。结果表明,质量和口径相同的PELE和动能弹以相同的速度垂直贯穿混凝土靶后,PELE形成穿孔的直径明显大于动能弹,而动能弹的剩余能量明显多于PELE。此外,对特定的弹靶系统,要达成最大的穿孔直径,存在最佳的着速范围。更多还原

【Abstract】 With the appearance of the plentiful concrete targets, it attracts more and more research and attention that projectiles penetrate into concrete targets. Making use of theoretic analysis and numerical simulation, the normal penetration of PELE and KE projectile into concrete target at a certain velocity is researched and analyzed. A comparison is made between the two processes, and it shows that there is a difference between the PELE and the KE, even under the same mass, caliber, and velocity. After perforation, the perforation diameter of PELE on concrete target is larger evidently than that of the KE. However, the remained energy of KE preponderates over PELE. As for specific projectile -target system, with a view to the biggest diameter of perforation, there stays optimal range of velocity.更多还原
