Finite Element Method is a very effective mathematical calculate method in engineering. It has been widely applied in various of engineering fields. With the constant improvement of engine design demands, the finite element method may be used in the design of major parts of engine and can meet the design needs of complex structures. The finite element modal analysis of an effective model has been done after building up its analytic model by applying modern CAD techniques. It is major way of current design of engine that the application of finite element mechanical model calculates stress and deformation in static state and real actual operation.
