Abstract >The traditional supercavitation projectile depends on its kinematics to damage targets. However, the bullet penetration ability is greatly restrained by the range. To improve the damage performance of underwater projectiles, the shaped charge and supercavitation technology are combined in this paper, which called shaped charge supercavitation projectile. The projectile is designed and analyzed through ANSYS/LS‐DYNA software in the preliminary stage. The simulation results turn out that the structures have many advantages with reasonable design. The paper divides the design into three steps: the first step is to design the shaped charge according to the requirements or shaped charge structure designed; the second step is to determine the optimum stand‐off that is obtained by numerical analysis. The stand‐off is set as the length of the projectile head; the third step is to calculate the cavitator diameter by the Logvinovich equation. These results will provide a new idea for the design of underwater weapons. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> >传统的超级挖掘弹丸取决于其运动损坏目标。然而，子弹渗透能力大大限制了范围。为提高水下炮弹的损伤性能，本文相结合了成型电荷和超级渗流技术，称为形状电荷超级挖掘射弹。通过初步阶段的ANSYS / LS-DYNA软件设计和分析射弹。仿真结果表明，结构具有合理设计的许多优点。本文将设计划分为三个步骤：第一步是根据设计的要求或成型电荷结构设计成型电荷;第二步是确定通过数值分析获得的最佳停滞状态。脱扣设置为弹丸头的长度;第三步是通过LogVinovich方程计算空穴直径。这些结果将为水下武器设计提供新的想法。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-29946/'>《Propellants, Explosives, Pyrotechnics》</a> <b style="margin: 0 2px;">|</b><span>2020年第4期</span><b style="margin: 0 2px;">|</b><span>共13页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Wang Kang‐Jian&option=202" target="_blank" rel="nofollow">Wang Kang‐Jian;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Rong Guang&option=202" target="_blank" rel="nofollow">Rong Guang;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Yi Wen‐Jun&option=202" target="_blank" rel="nofollow">Yi Wen‐Jun;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>National Key Laboratory of Transient PhysicsNanjing University of science and technologyNanjing 210094 P.R.
