Research on a method of hull form design based on wave-making resistance optimization


Zacytuj

In this paper, we consider an optimization of the hull shape in order to minimize the total resistance of a ship.The total resistance is assumed to be the sum of the wave resistance computed on the basis of the thin-shiptheory and the frictional resistance. Smoothness of hull lines is proved with mathematical procedure, in whichdifferentials of the hull lines functions are analyzed. The wave-making resistance optimization, involvinga genetic algorithm, uses Michell integral to calculate wave resistance. A certain hull form is generatedby the method using cross section information of a modified DTMB model ship 5415 and a comparativeexperiment is carried out. Experimental and calculation result show that the method is of good adaptabilityfor designing certain types of ships with excellent resistance performance.
