Abstract :The solid model and finite element models of cylinder head are given by means of the advanced CAD tech
niques , and convergence analysis of discrete errors of finite element model was also conducted. Further more , of this
temperature and stress fields of cylinder head under different working conditions were simulated. The calculated results is
helpful to find the places where failures might happen , and provide the information for improving cylinder head structure.
Keywords :Finite element method ;Diesel engine ;Cylinder head ;Structural analysis
