Aim To establish the parametric solid model based on feature for cylinder head of diesel and analyze the finite element model. Methods Feature technology is used to establish the parametric model. The finite element method is applied to calculate the modal parameters. Results The parametric model is successfully realized; the first four natural frequencies and the modal shapes are calculated. Conclusion The superiority over previous methods in the dynamic analysis of complicated structures is obviously seen
and a basis for the dynamic simulation study for the engine is provided.
