Cylinder Head Gasket

This paper focuses on discussing the application of FEA theory and method in calculation of composite structure strength between engine cylinder head and head gasket. Based on finite element analysis software, the integrated system of 3D CAD/CAE application software was developed for the finite-element analysis of the composite structure consisting of engine cylinder head and head gasket. By using the software system, several jobs, such as working condition analysis from preloading to outburst operation, structural analysis and steady-state thermal analysis, and thermo-structure coupling analysis, were carried out. The results studied in this paper provide a new idea and method for the finite element analysis of composite structure between engine cylinder head and head gasket.

Stress And Deformation

Considering the structure of some diesel engine cylinder head, its 3-D solid model and the finite element model is built, and after the load and constraint of is deal with, the stress and deformation the cylinder head with thermal-mechanical coupling is calculated with FEA ( Finite Element Analysis) software ABQUS. Analysis results find that: (1) the first main stress maximum value of cylinder head is up to 199.6MPa, which is less than 250MPa of the HT250 material ultimate tensile strength; (2) the deformation area is mainly in the flame face surface and fuel injector coxcombing, and the deformation of flame face is general symmetrical broadways and slightly large near the exhaust passage longways, while the deformation of fuel injector coxcombing is general symmetrical broadways and longways; (3) the structure design and strength of the cylinder head satisfy the design requirements.
