Patent number: 7171282Abstract: The present invention provides a shell plating developing method leading to reduction of the amount of machining and improvement of the efficiency in manufacturing the shell plating. In the shell plating developing method according to the invention, a shell plating lattice system is constituted, and the directions in which the curvature of a shell plating P at each lattice point of the shell plating lattice system is maximum and minimum are determined (s102). Also, lines extending in the directions in which the absolute value of the curvature is large and small are determined as a first connection line L1 and a second connection line L2 (s104). The first connection line L1 is developed as a straight line on a flat plate P? while the length of the first connection line L1 is maintained.Type: GrantFiled: March 18, 2003Date of Patent: January 30, 2007Assignees: The Cooperative Association of Japan Shipbuilders, National Maritime Research InstituteInventors: Kazuyoshi Matsuoka, Tadashi Matsukawa
