ABSTRACT

In this study, a simulation model was developed for the induction heating process in the upsetting forming of drive shafts for electric hydrogen vehicles. The local thickening of the drive shaft through upsetting is performed immediately after heating the shaft's end via induction heating, and an appropriate temperature distribution at this stage is crucial for ensuring the integrity of the drive shaft. Therefore, an analysis was conducted to investigate the effects of coil design on the heating characteristics using the induction heating simulation. The results revealed that two key variables— coil length and coil pitch—had significant effects on both the heating characteristics and the final shape of the material after upsetting. Based on the simulation results, the optimal coil design for induction heating was proposed, confirming that the desired variable cross-sectional drive shaft could be manufactured successfully.
