Sealing 성능 개선을 위한 Rocker Cover Gasket의 수치해석

In order to evaluate sealing performance of the rocker cover gasket, numerical analysis method using ABAQUS is applied. Characteristics of gasket material are obtained by the specimen test, such as tension, compression and stress relaxation, and a series of numerical analysis are carried out for 2D & 3D F.E models. From the analysis results, parameters related to sealing performance are studied. Finally, a optimized rocker cover gasket based on contact pressure and durability is developed and verified by showing its efficiency.
