Studies of Relationship between Contact Width and Leakage on Large Size of New Metal Gasket
In the previous study, the relationship between leakage and the contact width size that prevent leakage for 25A size of new metal gasket has been examined. In this study, large size of new metal gasket which are 50A, 80A and 100 A sizes were evaluated by using same approach of leak measurement and the relationship between leakage and the contact width. A new approach of leak measurement was performed to clarify the relationship between the presence of leak produced by the water pressure test and the amount of helium leak rate using helium leak test. Moreover, comparing the evaluation results of the relationship between the clamping load and the contact width by using the finite element method (FEM) analysis with the experimental results of the clamping load and the leakage, the contact width which affects the occurrence of leakages on new metal gasket was clarified. The results obtained for these gaskets indicated that the contact width is similar.
