查询词典 projectile

The explosively formed projectile with fins for a cover charge structure by LS-DYNA software which four covers were conglutinated on the liner was studied by three-dimensional numerical simulation. The mechanism of forming EFP with fins was discussed based on the curves of velocity and pressure vs time of the liners. A contrastive analysis was carried out on the three kinds of liners which include big-cone shaped liner, imperfect-sphere shaped liner and arc-cone shaped liner.

采用LS-DYNA对在药型罩上粘附隔板结构形成带尾翼型爆炸成型弹丸(explosively formed projectile，EFP)进行三维数值模拟，从药型罩微元压跨速度和压力的角度初步探讨了形成尾翼型EFP的机理，对同一直径的大锥角型、球缺型和弧锥结合型药型罩形成的尾翼型EFP进行了对比分析，三种结构药型罩均能形成较为明显的尾翼，其中大锥角型药型罩得到的EFP速度最高。
