Abstract

The flange structure parameters which influenced the contact pressure and effective sealing width of ring gasket were analyzed by numerical simulation method. The significance analysis on the flange structure parameters was done by orthogonal test method. The results showed that the maximum contact pressure of the male-female surfaces of the ring gasket increased with the decreasing the flange structure sizes. The significant influence sequence of the flange structure parameters to the key indexes is as follow: male flange outer end diameter>flange outside diameter>neck thickness>neck height>flange effective thickness. And the outer end diameter of the male flange had the greatest influence on the maximum contact pressure of the male-female surface of the ring gasket.

Key words： double wedge angle ring gasket; flange structure parameter; seal contact pressure; numerical simulation; significance
