Blank Design of Reinforcing Plate for Window Frame in Front Door Based on One-step Method
Blank design plays an important role in the process design of automotive sheet metal stamping forming,and it can directly influence the formability of a part.One-step method simplify sheet metal forming process into a simple load deformation process.The initial state and the end deformation configuration were analyzed based on the total strain theory.Combining the plasticity deformation theory with finite element method,the blank contour can be directly calculated from a given part.Taking the waist reinforcing forcing plate for window frame in front door for example,the initial blank contour can be obtained by one-step method,which can prove the speediness and correctness of one-step method.
