摘　　要：水下航行器(Unmanned Underwater Vehicle,UUV)在海洋战略中的作用越来越显著,但是现有UUV普遍存在工作时间短、续航里程小的问题,续航能力是UUV的主要短板之一。为研究UUV在水下停机后无动力悬浮待命以提高续航力的可行性,通过建立UUV空间运动模型、海水密度模型、UUV密封舱压缩模型、浮力材料压缩吸水模型,对UUV在水下将关键执行机构停机后的自由运动状态进行数值仿真。结果显示:UUV在海水密度呈正梯度变化的情况下可实现无控条件水下悬浮。The role of unmanned underwater vehicles(UUVs)in marine strategy is becoming more and more significant,but the existing UUVs generally have the problems of short working time and short endurance,among which,the endurance is one of the main shortcomings of UUVs.In order to study the possibility of UUV suspended without power after underwater shutdown to improve endurance,UUV space motion model,sea water density model,UUV capsule compression model,buoyancy material compression and water absorption model are established to conduct numerical simulation of the free motion state of UUVs after shutting down the key actuator underwater.The results show that UUVs can realize underwater unpowered suspension under the condition of positive gradient change of seawater density.
