| 摘 要： | 为了研究膛炸时弹丸壳体和身管的破坏效应,用双层金属圆管代替弹丸壳体和身管建立了简易膛炸模型,并运用LS-DYNA动力有限元程序对膛炸过程仿真,分别采取不同的装药方式和起爆方式进行了模拟.仿真结果表明,在不同的装药方式和起爆方式下,弹丸和身管破坏过程及最终破坏效果存在差异.采用的仿真方法和得到的结果可为进一步研究诸如发射... |

| Abstract: | To study the deformation and fracture form of cannon-shot and gun barrel,double-deck metal cylindrical tube was used to build a simple model of breech bursts.Then the breech bursts were simulated by LS-DYNA,using different TNT filling modes and detonation modes.The results showed the demolishing process and fracture forms of different breech burst types.The numerical simulation method and result can be reference to study some practicalities like the cannonball exploded in the gun barrel during shooting. |
| Keywords: | detonating deformation and fracture form numerical simulation |
