Prediction of Cylinder Deformation Considering Shear Slipping Behavior of Cylinder Head Gasket (Second Report)

- Study of Cylinder Head Gasket Modeling -

Abstract

We propose a new cylinder head gasket model for the precise prediction of cylinder deformation. The proposed model is based on the high-order deformation modes of cylinder head gasket with the material characteristics of rubber coating and metal plate. This improvement affects the shear behavior of the contact surface between cylinder head gasket and cylinder block. According to the comparison with experiment results, it is found that the proposed model increases the prediction accuracy of the frictional shear force and contact status of cylinder head gasket without matching parameters for experiment conditions. The proposed model provides a useful design method for cylinder head gasket and engine structure.
