Research on Heat Source Model and Numerical Simulation of High Frequency Induction Heating Forming

In order to simulate the temperature field of high frequency induction heating forming and improve the accuracy of numerical simulation,a heat source model for high frequency induction heating forming was established based on the characteristic of vortex distribution and head shape dimension of electromagnetic induction heating. The function expression of energy distribution was proposed in the process of establishing the model. The effectiveness of heat source model of high frequency induction heating forming was analyzed by using finite element analysis software. The results show that the simulation results of temperature field analysis agree well with experimental data. The peak temperature is located in head zone of electromagnetic induction heating. The peak temperature increases with the increase of output power and induction heating time.
