| 摘 要： | 采用ANSYS-AUTODYN数值模拟软件针对撞击速度在1 500~3 500 m/s内的平头分段杆侵彻效应进行研究，分析分段杆的侵彻效率和弹坑形状与分段杆的连接结构、间隔和撞击速度等参数的关系。结果表明，在一定的条件下，分段杆的侵彻效率比连续杆更优越。通过对公开报道的实验工况进行数值模拟，验证了数值模拟结果的有效性，对分段杆的侵彻机理研究及工程结构设计具有指导意义。

| Abstract: | The penetration performance of blunt segmented rods was studied with numerical simulations by using hydro code ANASYS-AUTODYN systematically,and the dependence of penetration performance on the connect configuration,shape,spacing distance,impact velocity of segmented rods was also investigated.The numerical results indicated that penetration performance of the segmented rods is significantly greater than the parent continuous rods under some conditions.Simulations on the tests from open literature validate ... |
