Abstract: | This paper presents a ship-hull plate forming way by pure line heating. The heating lines forming the required bending angle
is determined by curvature analysis method. Heating along the calculated heating lines results in bland plate with initial,
transverse curvature. Then, the plate with desired convex shape can be obtained by, heating in the longitudinal edge. This
is the whole forming process by pure line heating. This paper presents a method of plane development for ship-hull plate with
B-spline surface representation, and provides the shrinkage heating lines in the forming process. This forming way would facilitate
temperature control and make plate forming automatically easy. |
