Modeling Diesel Engine Cylinder Head Gaskets Using the Gasket Material Option of the SOLID185 Element
The modeling of diesel engine cylinder head gasket joints is complicated by the nonlinear response of the head gasket’s materials. Linearization of these material responses can lead to significant errors in the solution’s results. The 1-dimensional nonlinear approximation made by the Gasket material option of the SOLID185 element sufficiently captures the response of the nonlinear gasket materials while maintaining practical solution times for the large model sizes associated with multi-cylinder head gasket joint models. This paper will give an overview of the model building and assembly process used to create a head gasket joint model, describe the nonlinear nature of the materials used in the model, and present comparisons of the model’s results with experimental measurements.
