Optimization of New Metal Gasket Design Based on Contact Width Involving Contact Stress Consideration

Abstract:

The relationship of contact width and leakage had been found as design concept to optimize new metal gasket. By using this design concept, the limits of contact width for no leakage can be chosen. The optimize gasket shape can be developed by increasing of contact width. In this study, a gasket shape was optimized based on contact width as design concept and involving contact stress consideration. The design of experimentation (DOE) Taguchi method is used to analyses the effect of each parameter design and predict optimal design of new 25A metal gasket. The L18 orthogonal array was concerned to design experimental matrix for seven factors with three levels. The optimum design of gasket at 0 MPa mode is the model with OH = 4 mm, p₁ = 3.5 mm, p₂ = 4 mm, p₃ = 4 mm, t = 1.2 mm, R = 3.5 mm and h = 0.4 mm. The optimum design of gasket at 400 MPa mode is the model with OH = 3 mm, p₁ = 3.5 mm, p₂ = 4.5 mm, p₃ = 4.5 mm, t = 1.8 mm, R = 1.5 mm and h = 0.3 mm.
