摘要
为准确计算滑行艇在波浪中的水动力性能,基于粘性理论,采用随体网格技术、耦合求解运动方程,完成了滑行艇在迎浪规则波中运动响应的数值预报.对滑行艇运动响应结果采用时域和频域方法分析,给出了入射波的周期与滑行艇固有频率对滑行艇运动响应的影响分析结果,对数值计算值与模型试验值进行比较.结果表明,数值计算方法可以准确且高效预报滑行艇在波浪中高速航行时的运动姿态及水动力特性,为滑行艇设计提供指导和参考依据.
In order to accurately compute the hydrodynamic performance of planing craft in waves,the high-speed sailing of planing craft in regular head waves is numerically simulated with multiple degrees of freedom by performing sea keeping model experiments.In the simulation,the stickiness theory is adopted and the body-fitted mesh technique is employed.Based on the time domain and frequency domain analysis method of the motion responses of the planing craft,the analysis of the influence of the period of incident wave and the natural frequency on the response of planing craft has been finished.The numerical results are compared with the experimental data,and it is found that the numerical calculation method can accurately and efficiently simulate the motion attitude and the hydrodynamic characteristics of the planing craft in high speed navigation in waves,which could provide guidance and reference for the design of planing craft.
