水下弹药碰撞与弹道信号特点数值分析
Underwater ammunition collision and numerical analysis of ballistic signal characteristics
摘要
Abstract
In the operating environment, underwater rockets are prone to low-speed large angle - of - fall collisions. At this time the rocket body axial acceleration is close to the ballistic flow resistance acceleration, which leads to fuze false ignition. However, no relevant research has been published. In this paper, the ballistic and collision process of underwater rockets were simulated by LS-DYNA and FLUENT of ANSYS 14.0 for the acceleration characteristics. The results show that the low-speed col-lision axial acceleration is less than ballistic maximum acceleration, but the differences of the rocket body normal acceleration between these two situations are obvious. An acceleration-triggered composite detonation control method was presented based on the simulation results. The analysis shows that the simulation method is mature and highly reliable, and the problems existing in the data have reasonable explanation. The detonation control method can recognize the underwater rocket's collision signal and ballistic signal, and has high accuracy and can be applied in the design.关键词
