摘　　要：水翼辅助推进是利用水翼吸收船舶在波浪中摇荡运动的能量从而降低波浪增阻并提供额外推力的技术,其中绕水翼的环量流动对水翼所产生的力与力矩有着重要影响。为此,利用ANSYS-AQWA结合源面元分布法与平板摇荡翼速度环量力理论解,对安装有固定翼的S175船运动响应进行了数值模拟。计算结果表明,水翼能显著降低船舶在迎浪中航行时船舶的运动响应。Hydrofoil-assisted propulsion refers to the technology of absorbing the energy of the ship's motion in waves through hydrofoils to reduce the wave added resistance of the hull and provide additional thrust,in which the circulatory flow around the hydrofoils has an important effect on the generated forces and moments.For this purpose,numerical simulations of the motion response of the vessel S175 with fixed hydrofoils were carried out through ANSYS-AQWA in combination with the source distribution method and the theoretical solution of the oscillating flat-plate hydrofoil circulatory flow force.The computational results demonstrated that hydrofoils can significantly reduce the motion response of the vessel when sailing in head waves.
