摘要
针对海洋密度跃层严重影响潜艇水下变深操纵运动规律,易引发失控、掉深等险情,严重威胁潜艇航行安全,基于中国海密度跃层分布特征统计资料和潜艇空间运动数学模型,采用计算机仿真的方法,分析了正跃层和逆跃层分别对潜艇变深操纵的影响以及逆跃层中潜艇受扰后的自由运动规律,提出了相应的操纵注意事项和应对措施。结果表明,正跃层有利于潜艇保持深度和进行悬停操纵,若需转换深度长时间航行则应及时均衡潜艇;逆跃层对潜艇航行安全威胁最大,指挥员需密切关注海水密度及潜艇深度变化情况,深度发生异常时则应及时增速并均衡潜艇。
For pycnocline seriously affect the submarine depth changing motion law underwater,and threaten to the submarine navigation safety,the influence of positive gradient pycnocline and negative gradient pycnocline on submarine depth change steering,and the free movement rules in the negative gradient pycnocline after disturbance were analyzed by the means of computer simulation based on China sea pycnocline distribution statistics and mathematical model of submarine space motion.The corresponding control considerations and countermeasures were put forward too.The results show that the positive gradient pycnocline is beneficial to the submarine to maintain depth and to hover,and if it needs to change depth for a long time the submarine should be balanced in time.The negative gradient pycnocline poses the greatest threat to the navigation safety of submarines.Commanders should pay close attention to the changes of seawater density and the depth,and it will increase the speed and balance the submarine in time when the depth is abnormal.
