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.

Selection Of

The selection of measurements in multi-station machining systems is currently not a systematic process and it involves expert human intervention. In this paper, the recently introduced formal methods for quantitative characterization of measurement schemes in multi-station machining systems are employed in devising systematic measurement scheme synthesis procedures. The newly proposed synthesis procedures were applied in devising measurement schemes in the process used to machine a car engine cylinder head. It was observed that the measurement scheme synthesis procedure based on a genetic algorithm robustly outperformed the synthesis procedures based on the heuristics of successive measurement removal.

The paper presents modeling and calculations of multi-bolted connections at the assembly stage on an example of the engine cylinder head-block connection. The physical model of the connection was introduced as a combination of three subsystems: the set of bolts, the joined element and the contact layer between the joined element and the rigid support. The finite element method (FEM) was used for the modeling. Bolts were replaced with hybrid elements. The joined element was modeled with spatial finite elements. The Winkler model of the contact layer has been taken into consideration. The truth of the theorem has been examined, according to which non-linearity of the contact layer has a negligible impact on the final values of the bolt forces in the case of sequential preloading of the multi-bolted connection. The results of the calculations of a selected multi-bolted connection have been compared with the experimental results.
