FEM Analysis of a Diesel Engine’s Cylinder Head

Abstract:

The article aims at the cylinder head used in a high speed and higher-power diesel engine. In order to obtain the vibration characteristics and vibration frequency distributions. By means of modal analysis technology and finite element method (FEM), structural characteristics of the cylinder head using modal analysis is investigated. Firstly, a physical model of the cylinder head is built. Through the comparison of all the modal analysis results with different meshing densities, a tetrahedron ten-node element with length of 30mm is selected. Then finite element analysis of the model is taken by FEM software. The cylinder head’s modal parameters namely its natural frequency are calculated and its mode shapes are identified. The results can provide basis for the engine’s dynamic analysis and control of the diesel engine’s noise
