【摘要】 针对串联战斗部前级集群聚能装药对靶体预破坏以利于提高后级战斗部侵彻能力的问题,采用数值模拟的方式分析了不同靶体开孔形式对战斗部侵彻能力和靶体破坏模式的影响。从靶体应力波传播角度初步分析了战斗部对不同开孔形式靶体的破坏机理。结果表明,战斗部对预制孔洞靶体的侵彻深度要大于未开孔靶体,孔洞直径和孔径数量是影响侵彻深度的关键因素;相应的侵彻过程中的阻力得到了明显的降低。更多还原

【Abstract】 Aimed at the penetration efficiency increase of the second warhead in a tandem warhead because of the predamage of the first parallel shaped charge to targets,the numerical simulations were conducted on the effects of the different borehole modes in concrete targets upon the penetration efficiency of warhead and target damage modes.From the point of the stress waves spread in targets,the damage mechanisms of targets with different borehole modes were anaylzed.The numerical simulation results show that the depth of the pre-borehole target is greater than the integer target under warhead penetration.The hole diameter and number are the important factors for the depth of penetration.And the resistance under penetration was reduced.更多还原
