Abstract:

A reliable but cost-effective method is proposed to improve the FE strength analysis of stamping parts. In the proposed method, a mapping theory of mesh field variables is introduced to eliminate the difference of mesh density in heterogeneous codes using the mesh area of weighting factor method, and a database modification approach is developed to solve the difference of data organization between DYNAFORM and ANSYS. Last, the method is applied in the simulation of car wheel cornering test, the stress states of wheel with and without regard to sheet metal forming effects are comparatively analyzed, and the reliability and validity of the proposed method is verified by the experiment. The further analysis reveals that the thickness change and the residual stress occur during the drawing process of wheel disc, and the stress state of wheel is in asymmetric multi-axial stress during wheel cornering test. It is also revealed that the effect of thickness change on the stress history of steel wheel is different with the effect of residual stress, and their superposition effects are nonlinear with the applied stresses.
