Abstract

The objective of this research is to examine the deformation of the patch plate sheet of high-strength steel body structural components during the heating process to address the specific requirements of hot-stamped high-strength steels, which are extensively utilized in the automotive industry. By analyzing the temperature differential between the patch plate and the main plate in the heating process, as well as thermal stress and other influencing factors, a numerical simulation model was developed to investigate the deformation behavior of the patch plate sheet under various heating processes. The experimental findings indicate that warpage deformation occurs during the heating process of the patch plate sheet, and its extent is influenced by the heating temperature, heating method, and material properties. The study concludes that in the actual production process, the thermal deformation of the patch plate sheet should be minimized by mitigating the temperature differential between the heating of both sides of the patch plate and employing gradual sectional heating, in order to enhance production efficiency and quality.
