摘要
用自行开发的基于非均匀有理B样条的高阶面元法求解船舶有航速辐射问题,以修改的Wigley船型为例计算船舶垂荡和纵摇运动水动力和波形;将水动力计算结果与文献中的试验及数值结果进行比较,验证所用方法的有效性。
A NURBS-based high-order panel method was developed and applied to solve the radiation problem for a ship advancing at forward speed. Numerical calculations of hydrodynamic force and free surface elevation were performed for a modified Wigley ship in heave and pitch motion. The proposed method was verified by comparing the numerical resuits of hydrodynamic force with experimental results and other numerical results published in literatures.
