潜艇水下空间机动仿真与分析

目前，研究潜艇空间机动的运动特性、操纵控制方法和战术运用，已经成为提高潜艇的作战能力和生存能力急待解决的课题。该文介绍了潜艇平面运动操纵方程和空间运动仿真数学模型，并在此基础上编制仿真程序，对潜艇空间机动的三种操纵方式进行了分析比较；依据潜艇操纵性理论，通过对潜艇水下低速和高速空间机动仿真，对低速和高速时潜艇定常螺旋运动、定常潜浮运动进行了比较，并分析了航速对潜艇横倾的影响，得出了高速空间机动较低速空间机动的优缺点。

Simulation Study and Analysis on Underwater Space Motion of Submarine

Now, studying space motion characteristics, control method and tactical applications of submarine has become an urgent subject to improve fighting and survival ability of submarine. This paper presents the plane motion control equation and space motion equation. Based on the equations, the emulator is programmed, The paper analyses and compares three kinds of control methods of submarine space motion. Depending on theory of submarine manoeuvre, the paper compares submarine stationary spire motion and stationary submergence motion between low speed and high speed through simulation. Also this paper analyses how the speed effects transverse pitch of submarine and educes the virtue and defect of low speed space motion and high speed space motion.
