초록

The induction heating is more efficient for a plate bending because of its easy operation
and control of working parameters, compared with the heating by a gas torch. The existing
axis symmetric analysis method could neither handle initial curved plates nor be used in the
optimization of coil shapes because of its limit of an axis symmetric coil shape. But the
proposed method using some discrete part models and analysis processes could overcome
these difficulties and show more accurate results in temperatures and deflections of flat or
curved plates with initial curvature than those in the existing axis symmetric analysis
method. This method is composed of the multi-disciplinary analyses such as an electro
magnetic analysis, a heat transfer analysis and a deformation analysis based on inherent
strain approach per each step. Traditionally, the coil shape in the induction heating is
circular shape and it needs the moving process along heating lines. To overcome this, the
'Long Type Coil' with some linear parallel coils was proposed. It did not need the moving
process along heating lines and reduced the heating process time. The results of
experiments were compared with those of the simulation.
