Abstract: By establishing the finite element model for the automobile exhaust manifold assembly, it divided the model into many systems with freedom, used ABAQUS software to do a modal analysis, and obtained the exhaust manifold assembly of vibration frequency and natural vibration model. The analysis provides reference for designers to avoid resonance and it provides necessary conditions for fatigue analysis as well as response analysis.

Key words: ABAQUS；the exhaust manifold assembly；modal analysis；finite element
