基于海流速度和流向的水雷水中弹道建模与仿真

摘要

The complex ocean environment has very important interference on the underwater trajectory of the mine.To analyze the ocean current affection on the motion state of the mine,the quaternion method is introduced to resolve the problem of the singular solution in Euler equation,trajectory models are set up based on the quaternion method in lentic water; and the correctional models are set up based on ocean current direction.Trajectory is simulated under different ocean current velocity and direction,movement rule and dispersal rule are analyzed.Simulation shows that results are tally with correlated data and actual data of measure,can furnish references for battle operation and correlative task research.%发射水雷时,由于水下环境的复杂性导致水雷的水中弹道要受到多种干扰因素的制约,为分析海流速度和方向对水雷水中运动状态的影响,针对水雷由鱼雷管水平发射出管,在解欧拉方程易出现奇异性而难以求解的问题上引入四元数法,建立基于四元数法的水雷在静水中的弹道模型;分析海流影响下的水雷水中弹道,建立基于海流的水雷水中的弹道模型.仿真水雷在不同流速、流向下的弹道,分析海流流向与水雷出管速度方向异同时,水雷在水中的运动规律和散布规律.实例表明,仿真结果与有关资料和实际获得的数据相吻合,可为部队执行布雷作战使用提供参考依据.
