Research On High Frequency Induction Heating Forming Of Plate

Thermal stress forming is a important forming process of plate which is deformed. At present, the traditional approach to cause thermal stress is local heating by flame or laser. Due to a great deal of limitation of heating by flame or laser, a new thermal stress forming process——high frequency induction heating forming of plate is studied in this paper. This process heats by high frequency induction in place of flame or laser. Main research contents in this paper are developing the FEA model of high frequency induction heating forming of plate, and exploring laws of this process. Main research content as follows:(1) The multiphysics coupled FEA model of high frequency induction heating forming of plate has been developed. Under the condition of some certain technological parameters, forming results of plate can be predicted.(2) A experimental machine of high frequency induction heating forming of plate has been developed. This tester can be used for the experiment and production of high frequency induction heating forming of plate.(3) The reliability of FEA model has been verified by the experiment.(4) By means of the combined method of numerical simulation and experimental research,the laws that main process parameters impact on the bending angle of plate is gotten.
