The virtual manufacturing technique was applied to a forming of the the vibration damping oil pan. Experiments necessary for the computation such as the tensile test and the formability test were also performed. It was 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 a single step.<br/>

The design methodology and design evaluation of automotive oil pan dies for laminate sheet metal are discussed in this paper, The forming processes and design<br/> characteristics of the dies for laminate sheet matal based on the oil pan are first introduced, Thereafter, the design of the tools is seen with the explanation of auto-design program, which is developed for generating the drawings of die structures associated with 7 forming operation steps.<br/> Next. the design analysis of the tools for pursuing optimal designs. namely. forming analysis and structural analysis, are demonstrated. Sectional forming approach is employed for checking the formability. and elastic 3-dimensional FEM is used for assuring the strength. The design evaluation revealed the uniform stretching over the region and the safe strength of structure.<br/>

For the optimal design of starnping dies, formabilities during the forming processes and strengths against the forming loads are evaluated by sectional forming analysis program, SH-FORM2, and 3-D structureal analvsis system, IDEAS, In the formability analysis of hood inner panel dies, SH-FORM2 was able to predict the stretch and draw amounts and good agreement between measured and computed thickness strains was obtained. In the structural analysis, IDEAS revealed that stamping dies were designed to have enough stiffness inthe strength, though some parts of upper die, to which impact load is transmitted from the distance block of blank holder, need to be reinforced by the ribs.
