摘要
文章基于Bessho型三维移动脉动源格林函数(Three Dimensional Translating-pulsating Source Green Function,3DTP),开展了小水线面双体船(Small Waterplane Area Twin Hull,SWATH)耐波性数值求解方法研究,计入了对SWATH运动计算有较大影响的因素:两片体之间的兴波干扰、粘性阻尼和稳定鳍的影响。求解了SWATH-6A波浪中航行时的波浪力和纵向运动,通过与切片法结果和试验结果比较验证了计算方法。结果表明,基于3DTP的运动计算结果优于切片法结果,特别是纵摇运动预报较好,与试验值吻合更好。
The seakeeping performance of Small Waterplane Area Twin Hull（SWATH） was investigated by numerical method based on the Three Dimensional Translating-pulsating Source Green Function（3DTP）. Some factors that differ from conventional monohulls, but may have great influence on SWATH were included in the equations of motion, namely the wave interaction between the twin hulls, the viscous damping and the effect of stabilizing fins. The wave loads and motions of one SWATH vehicle named as SWATH-6 A were predicted. Numerical simulations were validated by comparison with both STF method and experiment. The result indicates that the motions are generally better predicted by the present method based on 3DTP than by the two dimensional strip theory,particularly for pitch motion.
