高速船在不利的横浪中容易产生冲浪运动。本文利用六自由度弱非线性模型研究了ITTC A2型渔船在设计阶段减轻乘浪的可能性。选择船舶浮心的纵向位置作为设计参数。该方法通过改变肋骨面积曲线来实现LCB的调整，并利用径向基函数（RBF）对船体曲面进行重构。利用该数值模型，对不同横摆角和佛汝德数情况下规则随浪中的乘浪运动进行了数值模拟。结果表明，通过调整LCB不能防止冲浪。但浮心向艏侧移动时的临界航速比向艉侧移动时的临界航速高，这主要是由于浮心向艉侧移动时的兴波阻力不同所致。
High-speed vessels are prone to the surf-riding in adverse quartering seas. The possibility of mitigating the surf-riding of the ITTC A2 fishing vessel in the design stage is investigated using the 6-DOF weakly non-linear model developed for surf-riding simulations in quartering seas. The longitudinal position of the ship's center of buoyancy (LCB) is chosen as the design parameter. The adjusting of LCB is achieved by changing frame area curves, and hull surfaces are reconstructed accordingly using the Radial Basis Function (RBF). Surf-riding motions in regular following seas for cases with different LCBs and Froude numbers are simulated using the numerical model. Results show that the surf-riding cannot be prevented by the adjusting of LCB. However, it occurs with a higher threshold speed when ship's center of buoyancy (COB) is moved towards stem compared to moving towards stern, which is mainly due to the differences on wave resistance caused by the adjusting of LCB.
