Prediction of Cylinder Deformation Considering Shear Slipping Behavior of Cylinder Head Gasket

Abstract

In this study, we calculated cylinder deformation under high pressure condition. Proposed model treated contact interaction between a head gasket and a cylinder block deck surface or a cylinder head considering frictional and shear behavior of the cylinder head gasket. The model was able to predict the changing margin of the deformation by different gasket structure type. According to the results, we found that transient phenomenon was occurred by changing contact interaction state from stick condition to slip condition regarding cylinder deformation toward cylinder pressure. Besides, we found that head gasket shear stiffness and frictional coefficient affected cylinder bore deformation.
