| 摘 要： | 利用数值仿真软件LS-DYNA3D，通过数值模拟方法研究了药型罩压跨、射流的形成、延伸和失稳断裂的全过程，数值模拟结果与实验结果吻合较好，得到了一套实用的数值模拟方法及材料模型参数，定性分析了大锥角的药型罩压垮过程，对形成杆式射流的药型罩结构设计具有一定借鉴意义。

| Abstract: | By three-dimensional finite element dynamic code LS-DYNA3D,the process of collapse,formation,elongation,instability and break-up of rod-like jet is simulated.The predictions of the simulation are in agreement with experimental data.A acceptable method of numerical simulation and parameters of material are obtained.The process of collapse about rod-like jet is discussed.It may be helpful for designing the configuration of shaped charge of rod-like jet. |
