| 摘要: |
| 根据一定的假设和简化处理,运用基于计算流体力学的VOF多相流技术,建立了进水过程的流体力学模型,针对前、后平衡舱空腔在静止情况下的进水过程进行数值模拟,得到了进水体积随时间的变化过程。在数学建模的基础上对分离前不同进水速度和不同初始速度作用下载荷AUV的弹道及分离后载荷的弹道进行了仿真。仿真结果与水池实验结果吻合较好,证明了弹道仿真结果的可靠性,对今后进一步的研究提供了理论参考。 |

| Abstract: |
| On the basis of certain assumptions and simplified processing, hydrodynamic model describing the process of the influent was gotten. The numerical analysis of the process of water injection into both frontal equili-brator and back one was done. And the variation of the influent volume with time was gotten. On the basis of the mathematical model, the paper simulated the trajectories of the underwater launch vehicle for different velocities of water injection before separation and for different initial velocities. The simulation results were in good agreement with the experiment results. The reliability of the trajectories simulation results was proved. |
