Abstract
It is the purpose of this paper to present a current research
project at Odense Steel Shipyard Ltd., Denmark. The objective of
the research is to find new mathematical methods for the design of
shell plates and apply these methods at the shipyard. The focus is
on double-curved plates as they are the most difficult to design
and produce, and often gives rise to gaps in the final assembly
stage requiring great expenditure of efforts to rectify.The
project aims at approximating a double-curved surface with a
(developable) cylinder surface using a new method for
approximation. By use of the Gaussian image of a given surface, we
determine a projection plane. In the orthogonal projection of the
surface onto this plane, a reference curve is determined by use of
methods for thinning of binary images. The cylinder surface then
can be derived with its directrix in the projected area and
rulings perpendicular to the projection plane.Application of the
results will be used to analyse the plate layout for production
and suggest better alternatives, and thereby minimize the heat
input.
