A Virtual Manufacturing of an Automobile Oil Pan Made From the Vibration Damping Steel Sheet

The virtual manufacturing technique was applied to a sheet-forming process. A virtual forming tryout of an oil pan with the vibration damping steel sheet (VDSS) was carried out. Experiments necessary for the computation such as the tensile test and the formability test were also performed. It was shown that the viscoelastic layer of the VDSS had almost negligible effect on the entire anisotropic behavior of the VDSS. It was also shown that the forming of an oil pan can be improved by controlling process parameters virtually inside the computer before the actual die tryout is performed. From the virtual die tryout, it was suggested that the two-step forming process of the oil pan may be reduced to one.
