| Abstract: | This paper present an iteration method, especially the matrix method, for solving a set of ship equilibrium equations by linearizing the non-linear problem. Besides, it illustrates two expressions of floating state diagram and corresponding computation method in order to rapidly and precisely determine floating state of ships under different loading conditions.The set of ship equilibrium equations is nonlinear and implicit. By using Vlasov's parameters, the problem in longitudinal plane is expressed by Following ship static theory, the formula for correcting waterline parameter in every approximation step can be developedThere is a great difference between our floating state diagram and Firsov's diagram. The later only shows the relation among ship geometric factors below waterline (molded volumes, longitudinal center of buoyancy, fore and aft draft). The former, however, can illustrate the ralation among displacement, center of gravity, fore and aft draft in equilibrium condition under floating and gravitational force. It is more advanced than Firsov's diagram, and so will be widely applied.This paper also gives an computating example for 50000 dwt tanker the "Xi Hu". |
