水动力系数敏感性分析在潜艇水平面运动模型简化中的应用研究

摘要

水动力系数敏感性分析是一种评估水动力系数对潜艇操纵运动影响程度的方法。本文根据水动力系数敏感性分析方法，计算某模型艇水平面回转运动战术回转直径的水动力系数敏感性指数，评估各水动力系数对战术回转直径的影响程度。并将敏感性指数作为水平面运动模型的简化依据。本文的研究为潜艇运动模型的简化提供了理论支持。也对潜艇操纵性设计和研究提供指导。%Sensitivity analysis of hydrodynamic coefficient is a method to assess the effect of hydrodynamic coefficient on the operation of submarines. The paper aims to calculate the hydrodynamic coefficient sensitivity index of the tactical rotational diameter at the water level for some submarine model by using sensitivity analysis of hydrodynamic coefficient. It assesses the degree of effect of hydrodynamic coefficient on the tactical rotational diameter and regards the sensitivity index as the simplification basis of horizontal motion model. The study provides theories for the simplification of submarine motion model and also provides guidance for the operational design of submarine.
