摘　　要：在无人水下机器人(UUV)朝着大型化的发展中,更多的大型UUV搭载X型舵。为了获取X舵大型UUV的水动力系数和可视化的流场矢量图,本文采用计算流体力学(CFD)的方式,首先在STAR-CCM+中以SUBOFF艇型为标准建模X舵大型UUV,再进行斜航、回转以及PMM仿真,拟合数据求得相应的水动力系数。最后将得到的无因次水动力系数和动稳定性系数和十字舵型SUBOFF作对比,结果显示X舵的大型UUV速度系数与SUBOFF较为一致,角速度系数相差在30%以内,加速度系数差别较大,整体系数绝对值高于十字型舵,在垂直面具有更好的动稳定性。该研究对搭载X舵的大型水下航行器的水动力性能研究和运动控制有重要参考意义。In the development of unmanned underwater vehicles(UUVs)towards larger sizes,more large UUVs are equipped with X rudder.To obtain the hydrodynamic coefficients and visualize the flow field vector diagram of large UUVs with X rudder,this study uses Computational Fluid Dynamics(CFD).First,an X rudder large UUV model is created in Star-CCM+based on the SUBOFF hull shape.Then,simulations for oblique towing,turning,and PMM(Planar Motion Mechan-ism)tests are conducted to fit experimental data and derive the relevant hydrodynamic coefficients.Finally,the obtained di-mensionless hydrodynamic coefficients and dynamic stability coefficients are compared with those of the SUBOFF with cross-rudders.Results show that the velocity coefficient of the large UUV with X rudder is similar to that of the SUBOFF,with angular velocity coefficients differing by less than 30%,while acceleration coefficients show greater discrepancies.The overall coefficients have higher absolute values than those of the cross-rudder design,providing better dynamic stability in the vertical plane.This study offers significant reference value for the hydrodynamic performance analysis and motion con-trol of large underwater vehicles equipped with X rudder.
