找到了接触宽度与泄漏量的关系，作为优化新型金属垫片的设计理念。利用这种设计理念，可以选择无泄漏的接触宽度极限。通过增大接触宽度，可以得到最优的垫片形状。在本研究中，以接触宽度为设计概念，并考虑接触应力，对垫片形状进行了优化。采用试验设计（DOE）田口法分析了各参数设计的影响，并对新型25A金属垫片的优化设计进行了预测。采用L18正交阵列设计7因素3水平的试验矩阵。0 MPa模式下垫片的优化设计为：OH = 4 mm, p1 = 3.5 mm, p2 = 4 mm, p3 = 4 mm, t = 1.2 mm, R = 3.5 mm, h = 0.4 mm。400mpa模式下垫片的优化设计为：OH = 3mm, p1 = 3.5 mm, p2 = 4.5 mm, p3 = 4.5 mm, t = 1.8 mm, R = 1.5 mm, h = 0.3 mm。
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.
