Contact Width Evaluation of New 25A-size Metal Gasket Considering Forming Effect

摘要：

In this study, gasket model is simulated by using two simulation stages which is forming and tightening simulation. By using forming effect, the limit of contact width on the previous model which excluded forming effect for no leakage was evaluated. Initial blank thickness is varied by adding 0％ (t0％), 5％ (t5％) and 10％ (t10％) of the final thickness of the gasket. The result shows that the final design shapes produced the defect occurred on the radius shape of convex contact. The lack of die fill defect is decreased with increasing initial blank thickness. The contact stress of forming models is higher than the contact stress of non forming models due to residual stress of forming effect. Based on contact width criteria, the non forming model is still valid for gasket design concept and more efficient for consuming the simulation time.
