FINITE ELEMENT ANALYSIS ON THE SEALING BEHAVIOR OF PROTRUSION O-RING FOR AUTOMOTIVE

There have been lots of cases that sealing has been assembled with sealing not connected to groove in flange etc. Sealing assembled with groove separated causes gas or oil to be leaked. Failure of parts resulting from damaged sealing entails a lot of expenses. This Article designed a protrusion in existing sealing to prevent sealing from being separated and examined strain and stress according to the size of protrusion through simulation analysis. It was found that protrusion of sealing with 1mm larger than the width of groove showed low strain and high stress, which suggests that the f
