Abstract
The hot stamping process and process parameters are investigated for a model of a B-pillar outer plate by numerical simulation. The feasibility of hot stamping forming process and its parameters are analyzed. The effectiveness of numerical simulation and the accuracy of hot stamping forming process and its parameters for B-pillar outer plate are proved by the hot stamping experiment and tensile tests. Three models are designed to analyze the effect of B-pillar in the vehicle side impact. It shows that hot stamping technology has the advantages in the field of lightweight and improving impact resistance. Through the research of the historical process of hot forming part, the residual strain characteristics of hot stamping parts is analyzed, the produce and mechanism of residual strain is explained, and the application method based on the forming history of hot stamping technology is provided.
