摘要
本文对潜艇六自由度空间运动方程中所包含的108个水动力系数,进行了全面的分析、实验测定及近似计算,得到了描述潜艇空间运动的简化模型。并在此基础上,通过数值计算方法,对潜艇在水下航向改变时的运动进行了计算机模拟,获得了较好的结果,为保持潜艇水下无纵倾定深转向,提供了较为简洁的实施方式,并为潜艇水下操纵及自动驾驶仪的设计提供了理论依据。本文还对典型的水动力系数进行了大量的变值计算,为进一步进行潜艇操纵性的研究提供了依据。
In this paper, all of the 108 hydrodynamic coefficients contained in the standard equations of motion in six degrees of freedom for submarine simulation determined by model testing or calculating are analyzed. Simplified equations for the motion of submarine are presented. Based on them, the motion of a submarine when turning underwater are simulated by numerical calculation and the result is satisfying. In order to keep the submarine turns underwater at constant depth and without trim, both manual and automatic control modes are provided. All these providea basis for the underwater manoeuvre and the design of the automatic controller of a submarine. Extensive changing value calculation for the typical hydrodynamic coefficients are carried out and the results would provide a basis for further study of submarine manoeuvrability.
