Simulation Analysis of 25A-Size Corrugated Metal Gasket Coated Copper to Increase Its Performance

Abstract

Previous study, researchers investigated on 25A-size corrugated metal gasket using material SUS304 and it modified. The elastic model design of corrugated metal gasket still leakage and need high axial force for tightening process. The purpose of this study is to analyze coated corrugated metal gasket by FEM simulation. Experimental result used for validating the data. The characteristic of coating material should softer than base material. The coating material will stick and fill in the surface roughness of gasket. The simulation result shows that contact width increase and contact stress decrease after the gasket coated by copper. It mean that the gasket performance increase to stop the leakage.
