基于无动力运载器规避弹道方案的可行性,建立了潜射导弹无动力运载器水弹道数学模型和海流模型,运用模拟退火法优化得出满足出水约束条件的预设偏航角可行域,并分别对艇速和海流影响下的规避弹道进行了仿真研究.仿真结果表明,发射艇速对规避弹道影响较为微弱;在预设偏航角可行域内偏航角越大,偏移距离则越大,且与规避方向相同的海流增大了预设偏航角可行域,使规避任务更容易实现,而方向相反的海流很可能对规避弹道产生颠覆性影响.仿真结论具有重要的工程参考价值.%Based on the feasibility of unpowered carrier-evasion trajectory scheme, underwater trajectory mathematical model of unpowered carrier of submarine-launched missile and ocean current model are set up, and the feasible region of the predefined yaw angles which meet exiting-water restriction conditions is obtained by simulated annealing approach, with the influence of submarine speed and ocean current, evasion trajectories are respectively simulated and researched. The simulation results show that submarine speed affects very slightly evasion trajectories;with the increase of the predefined yaw angle in the range of the feasible region the offset distance becomes lager,and the ocean current with the same direction to evasion direction makes the evasion task realized more easily,which enlarges the feasible region of the predefined yaw angles,but very probably does the ocean current with the opposite direction have subversive effect on the evasion trajectories. The simulation conclusion has important engineering reference value.
