摘　　要：针对高横流环境中灭雷具定深投弹的精准度难以达成,通过灭雷弹物理参数和海流环境构建灭雷弹数值计算模型,采用有限元法对投弹过程进行仿真,分析了初速和横流条件对灭雷弹弹道的影响。进一步以灭雷弹重心位置和尾部直径为设计参数,以弹着点位置误差为目标函数,结合粒子群算法对高横流条件下的灭雷弹运动进行联合仿真优化。结果表明:由于海水阻力较大,灭雷弹初速对弹道影响很小,横流的流速对弹道的影响较大;优化后的灭雷弹在下落时保持倾斜姿态,弹着点位置偏差降低约94%;建立的多目标优化模型为精准投弹设计提供依据。Difficulty in achieving the accuracy of depth determination for mine extinguishing devices in high cross flow environments,a numerical calculation model for mine extinguishing bombs(MEB)was constructed based on their physical parameters and ocean environment.The finite element method was used to simulate the process of bomb dropping,and the effects of initial velocity and cross current conditions on the trajectory of mine extinguishing devices were analyzed.Further take the center of gravity position and tail diameter of the mine extinguishing bomb as design parameters,and the impact point position error as the objective function.Combine PSO algorithm to perform joint simulation optimization on the motion of mine extinguishing bombs under high cross flow velocity conditions.The calculation results show that Due to the high resistance of seawater,the initial velocity of minesweepers has little impact on the trajectory,while the cross flow velocity has a greater impact on the trajectory.After optimization,the mine extinguishing bomb maintains a tilted attitude when falling,and the deviation of the impact point position is reduced by about 94%.The established multi-objective optimization model provides a basis for precise missile delivery design.
