Abstract:
A method for calculating a heating procedure of a linear heating, the method comprising the steps of:determining a distribution of bending principal strains for giving a target shape of a curved surface; dividing calculation grids along directions of the bending principal strains; dividing the directions of the bending principal strains into both a direction of a maximum bending principal strain and a direction of a minimum bending principal strain for each of the calculation grids; determining a heating condition for heating a plurality of heating lines perpendicular to the direction of the maximum bending principal strain, the heating condition defying the maximum bending principal strain; obtaining membrane strains generated accompanying with heating the plurality of heating lines under the heating condition from a database, the database including a relation between the heating condition and deformation components; calculating a distribution of membrane strains required for achieving a deflection of the target shape of the curved surface in consideration of a distribution of the membrane strains obtained from the database; selecting a heating condition satisfying both the maximum bending principal strain and the calculated distribution of the membrane strains; and determining a heating procedure under the selected heating condition.
