干扰力作用下潜艇近水面运动的仿真

潜艇近水面运动时受一介波浪力和二阶波浪力的影响较大，本文对一阶波浪力、二阶波浪力和海流力进行了数值计算，然后把这些干扰力作为干扰项加入静水中的潜艇六自由度运动方程得到潜艇近水面运动模型。最后对潜艇近水面运动模型和压水及操舵对消除波浪力的影响进行了仿真分析，仿真结果与实际情况吻合，说明文中提出的潜艇近水面运动仿真模型是合理有效的。

Simulation of Submarine Near-surface Motion under Disturbance Force

Near-surface motion is a very important cruise state for a submarine. A model of submarine near-surface motion is presented in this paper. The first order and second order wave force are regarded as the primary factors in disturbing the submarine state near surface, and are calculated in the paper. In order to model the submarine near-surface motion, the first order and second order wave force, as interference factors, are added into the 6 DOF equations of submarine. In the last part of this paper, we simulate the submarine near-surface motion with the presented model. Moreover, it is also discussed how to minimize the effect of the wave force through shifting ballast water and maneuvering the rudders.
