The purpose of this paper is to conduct a seakeeping analysis of planing craft under regular wave with large wave height. To obtain a reliable numerical method to simulate the sailing of planing craft in waves, Reynolds-averaged Navier–Stokes (RANS) solver and overset method are adopted. The motion response and resistance of the planing craft USV01 in regular wave were numerical predicted and compared with the corresponding seakeeping experimental tests. The results show that the numerical method has high accuracy. For further study, a new planing craft whose name is improved vessel is selected for simulation, the low steaming of the USV01 and improved vessel in regular wave with large wave height was simulated, and the seakeeping of the two vessels was studied. The analysis about the influence of wave length on the motion response and navigation configurations of the improved vessel under regular wave was carried out. Meanwhile, the influence of speed on different navigation configurations of the improved vessel was also analyzed. The improved vessel can provide better seakeeping, and a reduction in the speed of the vessel will benefit its seakeeping, irrespective of its navigation configuration.

大浪高下滑行艇的耐波性分析

本文的目的是对大浪高的规则波浪下的滑行艇进行耐波性分析。为了获得一种可靠的数值方法来模拟滑行船在波浪中的航行，采用雷诺平均纳维-斯托克斯 (RANS) 求解器和叠加方法。数值预测了 USV01 滑行艇在规则波浪中的运动响应和阻力，并与相应的耐波试验测试进行了比较。结果表明，该数值方法具有较高的精度。为进一步研究，选择一艘名为改进型船的新型滑行艇进行仿真，模拟了USV01和改进型船在大波高规则波浪中的低航速，并对两艘船的耐波性进行了研究。分析了波长对改进船在规则波浪作用下的运动响应和航行构型的影响。同时，还分析了航速对改进船不同航行构型的影响。改进后的船舶可以提供更好的耐波性，无论其航行配置如何，船舶速度的降低都将有利于其耐波性。
