Abstract In order to solve the problems of bending and forming difficulties and poor forming quality of slotted high-strength steel plate with high thickness-to-width ratio at room temperature, induction heating technology is introduced to carry out local thermal bending and forming. A three-dimensional electromagnetic-thermal coupling simulation model was developed using finite element software to analyze the local induction heating process of high-strength steel plates with slots, and induction heating experimental validation was carried out to verify the reliability of the simulation model, with a maximum error of only 8.3%. Comparing local induction heating and overall heating bending forming schemes, the results show that:maximum stress is reduced by 25.7% and 27.44%, while rebound decreases by 10.42% and 10.41% respectively, compared to room temperature. The local induction heating internal maximum temperature difference of 144.34 ℃ increases the maximum stress by 1.03% and increases the springback by 0.57% compared to the temperature difference of 27.56 ℃. The results indicate that higher temperature uniformity achieved through local induction heating enhances forming accuracy. Furthermore, the study investigates the effects of varying current, frequency, and the thickness-to-width ratio on the temperature field distribution of the high-strength steel plates. It is found that as the current, frequency, and thickness-to-width ratio increase, the temperature peak also rises. Notably, the current and thickness-to-width ratio significantly affect temperature uniformity, while high-frequency currents adversely impact heating uniformity.
