潜艇垂直面波浪力计算与运动仿真

Computation of Motion and Wave Forces for a Submarine in Vertical Plane

为对潜艇在垂直面波浪力作用下的运动规律进行研究,基于PM谱长峰不规则波,采用Hirom近似公式计算垂直面波浪力。以某典型潜艇为对象,基于潜艇操纵运动线性模型,叠加波浪力,进行了潜艇近水面潜浮运动仿真。分析了不同浪向、波高、初始潜深、航速条件对潜艇潜浮运动响应的影响。进行了波浪干扰下潜艇操舵运动响应仿真,分析了波浪对操舵运动响应的影响。仿真结果能够较为真实地反应潜艇在垂直面波浪力干扰下的运动情况。计算模型与仿真程序系统满足检验的需求。

To survey the submarine vertical motion under the wave,Hirom wave force approximate calculation formula is used to calculate the wave forces in vertical plane motion with the PM’s waveheight energy spectrum.Based on the linear model of submarine,the motions and waves forces of a typical submarine in the transient responses in the time domain are given in a several submerged depths,wave height,wave directions,submerged depths and speeds.The good agreement of the numerical results with the simulation shows that the numerical method of this paper is valid and can satisfy the need of verification
