为研究水下接触爆炸产生的高速破片在水中的侵彻特性，针对3.3 g立方体破片进行了水下弹道试验，结果表明：破片的侵彻阻力系数受形状的影响较大，撞击隔板时产生压缩波使破片产生墩粗和侵蚀，造成破片迎流面积的增加和质量的下降，从而使破片在速度较高时侵彻深度反而下降。%In order to study penetration properties of high velocity fragment produced by underwater contact explosion, underwater ballistic experiments of 3.3 g cubic fragment was carried out, the results show that resistance coefficient of fragment is significantly influenced by the fragment shape. When the fragment crash on the steel plate, it will bring about great compress wave which makes fragment generate mushrooming and erosion, so the incident flow area increases and the weight decreases, consequently the underwater penetration ability of the fragments decrease with the increasing of velocity.
