On the Imitative Heating Conditions of Simulator for Heat Bending

Abstract

In the previous report, the authors had proposed an estimating method of deformation using PC in the heat-bend process for ship hulls. In this method, the shape of heated plate model was calculated by the 3-dimensional elastic analysis, omitting heat conduction analysis and plastic analysis. In this study, we have reported in regard to the setting method of the imitative heating conditions in the imitative heat-bending simulator. The imitative heating conditions are obtained by heat conduction analysis with moving imitative heating area. The compelling displacements for simulation calculate from maximum temperatures of surface and back-face. And we have showed the simulated results of the saddle-shaped shells using imitative heating conditions. These heating conditions have brought about very good results.
