Intelligent optimization design of wave-piercing bow lines for planing craft
摘要
Abstract
[Objective]The bow lines of a planing craft have a significant influence on its seakeeping per-formance,making their intelligent optimization design necessary.[Methods]This study focuses on a certain type of wave-piercing bow planing craft and uses the stem angle,second-order curve shape factors,and co-ordinates of the knuckle line bow control points as parameters for driving the deformation of the bow lines and carrying out the parametric modeling of the bow.It validates numerical calculation methods based on model test results and establishes a surrogate model according to the numerical results.It optimizes the still water res-istance and motion response amplitude in regular waves at a speed corresponding to a volume Froude number of Fr∇=2.7,and explores bow designs that balance resistance and seakeeping at the designed speed.[Results]The results under the constraint show that the still water resistance and the average wave-making resistance increase does not exceed 12%and the optimized hull form sees a reduction of about 20%in acceleration amplitude,heave amplitude,pitch amplitude,and heaving compared to the initial craft.[Conclusions]By optimizing the bow lines,the planing craft's low resistance is ensured while improving its motion response in regular waves,providing an intelligent optimization design method for planing craft lines.关键词
