Abstract:A new technology, utilizing electromagnetic force to promote deformation of ship hull plate during line heating process, is called electromagnetic force assisted line heating (EFALH), which can improve efficiency and accuracy of plate deformation. Some key issues are solved in the numerical simulation of EFALH to study this technology and design processing parameters. These issues include implementing multi-physics coupling, establishing three-dimensional finite element model, and analyzing thermal boundary conditions. Optimization analysis of relation between the auxiliary effect of electromagnetic force and the temperature of steel plate is introduced, and main technological parameters for EFALH are designed, providing guidance for the experiment.
