Determination of Hull Form Parameters of Large-Scale Ship Based on Synthesis Optimization of Ship Navigation Performance

A method is introduced for the determination of hull form parameters based on synthesis optimization of ship navigation performance in complicated navigation condition and a relevant program was made.The computation results show that the method is reasonable and the program is stable and reliable.Applying this method,the feasibility distribution function of each design variable can be determined.Change trend of optimum integrative ship navigation performance along with each design variable also can be drawn directly.This provides an applicable approach for the quantity comparison among the contributions of design variables to ship integrative performance and the determination of hull form parameters of ship with optimal integrative navigation performance in different navigation state,and lays a useful foundation for synthesis evaluation of ship design project,the determination of hull form parameters and the improvement of ship design efficiency.
