| 中文摘要: |
| 利用ANSYS/LS-DYNA软件对钨球、钢球两种预制破片材料的速度及飞散情况进行数值模拟,分析研究了钨球、钢球预制破片的速度、加速度和位移的数值模拟差异。结果表明采用钨球作为破片材料更合理。 |
| 英文摘要: |
| Using ANSYS/ls-dyna software of tungsten ball, steel ball two kinds of preformed fragment velocity and distributing materials are numerically simulated and analyzed based on the tungsten ball, steel ball preformed fragment velocity, acceleration and displacement of the numerical simulation. Simulation results are as follows, in determining the warhead charge mass and charge size cases, such as the shape, for the same shape, material for tungsten and steel preformed fragment, the starting time of the displacement of the two phase after the explosion is not much difference, tungsten ball velocity and acceleration are smaller than steel ball, but the duration of the tungsten ball acceleration is longer than steel, tungsten ball kinetic energy is also larger than the steel ball. The results show that the tungsten ball as a broken piece of material is more reasonable. |
