An Algorithm to Determine Heating Lines for Plate Forming by Line Heating Method

Abstract

The line heating method is a popular technique in shipyards to form ship hulls. This paper presents a new algorithm to determine heating lines for the simulation of a line heating process. The important feature of this algorithm is that it calculates the principal curvatures of the deflection difference surface that represents the shape difference between a target surface and a surface in fabrication, and uses a convergence index. Several trials of typical surface types show its usefulness and good practical applicability.
