چکیده:   (10564 مشاهده)
So far many case-study researches have been undertaken to propose suitable models for hull optimization of planning high-speed crafts. In this paper a systematic and generic method is illustrated for the first time to introduce the optimized hull form of craft considering the desired speed and weight. Using semi-empirical Savitsky's method, optimal geometrical parameters of planning high-speed craft are defined to minimize the hydrodynamic resistance. Of course some variants i.e. beam, deadrise and the distance of center of gravity to transom and two objective functions are introduced for hull optimization via Pareto-based genetic algorithm. The first objective function is the ratio of pressure and frictional resistance summation to displacement and the second one is the ratio of water spray's wetted area to displacement volume powered two-thirds. Optimization involves constraints such as: governing limitations on Savitsky method, hydrostatic stability, proposing instability and corkscrew dynamic stability. Finally a bunch of variants optimal quantities are presented to be applied in conceptual designing of high-speed monohull crafts.
