| Abstract: | Dynamic properties of the coach are analyzed based on finite element method and the effect of engine exciting force on the coach vibration is researched.The finite element model for the coach is established,and the free-state modal analysis of the coach is carried out.Harmonic response is analyzed based on the modal analysis,considering separately the vertical and horizontal excitation of the engine operating conditions.The vibration of various parts of the coach is studied through displacement response of the body caused by the harmonic power of engine. |

| Keywords: | modal analysis finite element dynamic property harmonic response analysis |
