无人反潜平台空投入水冲击仿真分析

Simulation and Analysis of Water Impact on Unmanned Anti-Submarine Platform

摘要: 空投无人反潜平台具有效率高、机动性好、突击性强等优点，是无人反潜的重要发展方向。无人反潜平台通过空投方式入水时，其冲击特性对平台结构完整性和作战效能具有重要影响。本文首先介绍了分析的基础理论和方法，随后通过数值模拟详细探讨了典型入水速度与入水角度对无人反潜平台冲击载荷的影响。研究结果表明，随着入水速度增加，平台遭受的冲击载荷显著上升，尤其在结构局部区域的压力峰值也随之增大；而在恒定速度下，垂直入水的冲击载荷明显超过倾斜入水。这些发现为无人反潜平台的设计、结构强化及入水操作提供了重要的理论指导和技术参考。

Abstract: Air-dropped unmanned anti-submarine platforms have the advantages of high efficiency, good mobility and strong surprise, which is an important development direction of unmanned anti-submarine. When the unmanned anti-submarine platform enters the water by air-dropping, its impact characteristics have an important impact on the structural integrity and combat effectiveness of the platform. This paper firstly introduces the basic theories and methods of the analysis, and then through numerical simulation, the effects of typical water entry speed and water entry angle on the impact load of the unmanned anti-submarine platform are discussed in detail. The results show that with the increase of water entry velocity, the impact load suffered by the platform rises significantly, especially the pressure peak in the localized region of the structure increases; while at constant velocity, the impact load of vertical water entry is significantly more than that of inclined water entry. These findings provide important theoretical guidance and technical reference for the design, structural strengthening and water entry operation of unmanned anti-submarine platforms.
