Method for estimating ship resistance performance using regression analysis

摘要

The present invention relates to a method for estimating the resistance performance of a ship, and according to the present invention, the main specifications of a limited number of ships (ship width (B), draft (T), waterline length (LWL)) in the basic design of the ship, In order to calculate the surplus resistance coefficient of the relevant ship and estimate the resistance performance by using the longitudinal buoyancy center position (LCB), square coefficient (Cb), etc.), a model test on the main specifications of the ship through a model test The results are collected to build a database (DB), and the interval for regression analysis is classified to select candidates for the dependent variable and the independent variable, respectively, and the independent variable and the regression equation are analyzed through correlation analysis between the dependent variable and the independent variable. The final regression equation is completed by defining the shape and calculating the regression coefficient by performing a nonlinear regression analysis using the shape of the determined regression equation, and calculating the residual resistance coefficient and estimating the resistance performance using the completed final regression equation. By being configured to perform a series of processing processes performed by a computer or dedicated hardware, the ship resistance performance is estimated faster and easier than conventional methods, and thereby, a more accurate ship design can be achieved. A method of estimating ship resistance performance using analysis is provided.
