摘要
在微幅波假定下,以Wigley数学船型为研究对象,利用无限水深三维移动脉动源(Haskind源)格林函数及面元法,建立规则波中顶浪航行舰船的绕射兴波波形及压力分布的计算模型;实现Haskind源格林函数中奇点的积分处理,并编制计算程序进行验证;最后对舰船的绕射波形及压力场分布进行分析。
Based on the assumption that the regular wave amplitude is small and researching object is Wigley ship model, a mathematical model of calculating diffraction wave pattern and pressure distribution caused by the moving ship in regular wave is established by using three-dimensional translating pulsating source （Haskind source） Green function with forward speed for infinite water depth. The integral method with singularity in Haskind source Green function is managed, and computing program is compiled to validate the method. Finally, the diffraction wave pattern and pressure distribution of ship are preliminarily explored and studied
