摘　　要：以经典的SUBOFF潜艇模型为研究对象,运用商业软件STAR-CCM+收集和分析该艇的速度信息,计算作用在艇体上的水动力。分别进行了斜航运动与纯横荡、纯摇艏运动仿真,求取相应的水动力系数。给出在4.5kn与6.5kn航速下的斜航模拟试验中模型所受的垂向力与摇艏力矩,对它们与速度的关系进行拟合,计算相应的水动力系数。对模型进行纯横荡与纯摇艏数值模拟,通过拟合曲线求得相应的水动力系数。该研究对进一步研究无人潜水器水动力性能和运动控制具有重要参考意义。In this study,the classical SUBOFF submarine model is used as the research object,and the commercial software STAR-CCM+is used to collect and analyze the velocity information of the submarine.Under navigation conditions the data of velocity and forces were collected and calculated to reflect the dynamic characteristics of the submarine.Simulations of oblique motion,pure sway,and pure yaw motion were conducted respectively,and the corresponding hydrodynamic coefficients were obtained.This study will provide a reference for further research on the hydrodynamic performance and control of unmanned underwater vehicles.
