Abstract

The invention relates to a method and a system for establishing a user-defined three-dimensional ship model. The method comprises the steps of obtaining ship parameter data and establishing a three-dimensional ship model; obtaining hydrostatic gauge data, and finely processing the established three-dimensional ship model; obtaining propeller data and establishing a propeller model, and adding the established propeller model into the finely processed three-dimensional ship model; and obtaining real-time status data of the ship according to the three-dimensional ship model, and computing the floatation condition, stability and strength of the ship by using an algorithm. The three-dimensional ship model is established by using the ship parameter data, insufficient continuity of the hydrostatic gauge data can be compensated by continuity of the three-dimensional ship model data, the established three-dimensional ship model is amended by the high-precision hydrostatic gauge data, and thereby the three-dimensional chip model is closer to the real ship data, and truth and computational accuracy of the three-dimensional ship model are improved.

Description

technical field [0001] The invention relates to the field of ship model building, in particular to a method and system for building a custom three-dimensional ship model. Background technique [0002] The current floating load calculation relies on the hydrostatic table provided by the design unit. The amount of data provided by the hydrostatic meter is limited, and it is necessary to interpolate the data to obtain the actual data. The data loss brought about in this process affects the accuracy of floating state calculation. Calculation of stability and longitudinal strength depends on partial calculation results of floating state calculation. The loss of floating state calculation accuracy causes the accuracy of all modules of ship loading calculation to decline, which has a great impact on the operation safety of ships. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, provide a kind of construction m...
