基于刚性网格法的潜艇水动力数值计算

通过对潜艇六自由度空间运动方程进行分析，得到了直航阻力运动、垂直面变漂角运动、水平面变漂角运动的空间运动方程。利用Suboff模型，基于刚性网格法，通过设定计算域的运动形式，实现了潜艇直航阻力运动、垂直面变漂角运动、水平面变漂角运动的数值模拟，通过对计算结果进行拟合得到了线性水动力系数和非线性水动力系数，通过与相关试验结果进行对比可知，计算误差在7%左右。

Research on the electromechanical actuation system for submarine outboard

Through analysis of submarine six degrees of freedom space motion equation, the direct resistance move-ment floated, vertical motion, horizontal angle of the space motion equation of angular motion. SUBOFF model, based on the rigid grid method, through setting calculation domain form of exercise, has realized the submarine direct resistance move-ment, vertical plane change drift angle motion, the horizontal drift Angle motion of the numerical simulation, based on the calculation results for fitting the hydrodynamic coefficient of linear and nonlinear hydrodynamic coefficients, by comparing with relevant experiment results, the calculation error is about 7%.
