Abstract


Five catamaran as a high-performance ship , good prospects for development . Five in the body and the body of the ship after two contralateral body exists between the complex wave interference, and each side of the body line , layout, and other changes to its wave resistance are closely related. This paper discusses the five trimaran wave resistance calculation methods discussed ship, front and back body layout changes on wave interference, find information about the law gives the right catamaran hull form optimization of five configurations and conclusions with reference value , specifically divided into the following sections: I. based on Noblesse new theories and Michell thin slender ship ship theory , the preparation of the ship wave resistance calculation program analyzes the scope between the two approaches and common , in order to further the these two methods applied to multi- trimaran wave resistance calculation basis. Second, based on Noblesse new theories and Michell thin slender ship ship theory, gives a trimaran wave resistance calculation formula and an example to wigley calculated trimaran trimaran wave resistance , and the two methods the results compared with the experimental values ??, proved that the calculation methods and programming for the correctness , discusses two methods forecast wave interference scope and inadequate. Third, based on Noblesse new theories and Michell thin slender ship ship theory, gives five trimaran wave resistance formula discussed catamaran Wigley five main dimensions of the rear side of the body changes the impact of the wave resistance , front and rear body layout for wave interference, based enumeration method gives the sheet body layout relating to law . Four to five SWATH catamaran hull form as the main body, slender body as the front and rear body , changing the front and rear body of the ship and layout to calculate the wave resistance , these factors from five body for SWATH boat wave interference and influence of wave resistance .
