Document Type and Number:
Japanese Patent JP5602326
Kind Code:
B1
Abstract:
PROBLEM TO BE SOLVED: To provide a technique for automatically specifying a closed section on a cross section of a ship, in a step for designing the ship.SOLUTION: A ship design support program extracts closed section candidates by tracing points and sides forming an independence graph on a cross section of the ship, in a bi-direction, and determines areas of the respective closed section candidates, by a cross section 0-th moment. In consideration of directions tracing the sides, an area of outside (rear side) of each closed section candidate, is determined, therefore the acquired area becomes a negative value. By deleting the closed section candidates whose cross section 0-th moment becomes a negative value, correct closed section candidates can be extracted. By deleting the closed section candidate whose area becomes equal to or less than 0, the closed section can be specified.
