潜艇掉深现象的特点与判定方法

Characteristics and judging method of falling deep of submarine

[目的]为有效判断潜艇是否存在掉深现象,[方法]建立潜艇水下运动模型,利用实验数据验证模型运动精度;模拟潜艇掉深现象,并进行运动特性分析;提出在不同航速下存在临界静载力的设想,通过计算验证这一设想。研究潜艇掉深的判别方法,提出将深度速率■H/■t 和纵倾变化率■θ/■ t 作为潜艇出现掉深的判据。[结果]能够快速有效地判断潜艇是否存在掉深危险。[结论]对潜艇安全操纵有一定的参考价值。

[Objectives] In order to judge whether there is a falling deep situation on submarine,[Methods]a underwater motion model of submarine is established,and the motion accuracy of the model is verified by experimental data;the falling deep of submarine is simulated and the motion characteristics are analyzed;the assumption that there is a critical static load at different navigation speeds is put forward,and the assumption is verified by calculation. The method of judging falling deep of submarine is studied,and the depth rate ■H/■t and pitch change rate ■θ/■t are used as the criteria for danger of falling deep of submarine.[Results] It can quickly and effectively judge whether the submarine is in danger of falling deep.[Conclusions]It has certain reference value for safe operation of submarine.
