【Abstract】 In order to study induction heating mode of ship curved plate,the change discipline of plate′s temperature and deform was analyzed by experiments and numerical analysis in respective heating periods.As for discontinuous heating method,the optimal work time parameter was provided.Current intensity and frequency in heating process were surveyed by Rogowski coil.The results of experiment and numerical simulation were identical,which means the numerical simulation was correct.The result reveals that distributing the heating periods regularly and taking the discontinuous heating method can obtain the expected forming,save energy effectively,and increase the heating effect.更多还原
