MATHEMATICAL MODEL FOR CALCULATING THE MASS OF THE METAL HULL OF A COMBINED VESSEL
Abstract
The total displacement and maximum deadweight for ships calculation is impossible without the mass of the metal hull accurate determination . Its value is influenced by the class, type of vessel, architectural and design features, and operating conditions that are expressed in providing General and local strength. All this must be taken into account at the initial design stages, since even minor errors in the specified mass calculation have a strong impact on the empty displacement final result . In this paper, the mathematical model of predicting the component loads for the ship combined mass, including the surface ship theoretical generation, the case elements spatial layout, the hull structure the compartments and ties actual size calculation of and on the basis of the mass itemized calculation. The main empirical formulas that make up the mathematical model content and the test calculations results are presented.
