초록
The fabrication of curved hull plates is a critical process in shipbuilding, affecting both the structural integrity and hydrodynamic performance of vessels. This study investigates a hybrid forming method that combines induction heating and multi-point press forming to improve the accuracy and efficiency of curved plate production. The forming experiments were performed under various heating and pressing conditions to examine their effects on deformation behavior, forming accuracy, and surface quality. The results indicate that the hybrid forming approach effectively reduces processing time, minimizes spring-back, and enhances the precision of the formed geometry compared with conventional mechanical forming. These findings demonstrate the potential of hybrid forming as an efficient and reliable technique for manufacturing complex hull structures in modern shipbuilding.
