海况干扰下潜艇六自由度运动分析
Analysis of six-degree-of-freedom motion in submarines under sea disturbance
摘要
Abstract
In order to compensate for the limitations of actual conditions in sea experiments, and to test on land the equipment that can be affected in a submarine motion, in this paper, we investigate a six-degree-of-freedom motion of submarines, including the submarine’ s direct navigation and turning movements in still water and the marine en-vironment. By analyzing the force of a moving submarine using the basic model of ocean waves and currents, we es-tablished a six-degree-of-freedom motion equation of submarines under ocean wave disturbance. Based on a subma-rine’ s hydrodynamic coefficients, which we collected and then corrected in our experiments, we could determine the submarine’ s line and angular movements, and could thus analyze its direct and turning movements. Simulation results can realistically reflect the interference in the movement of submarines in the marine environment, and thus meet the need in practical engineering to test equipment.关键词
