The practicality and reliability of computation model are the key problems in model building. The dynamic model of the linear system does not adapt to the nonlinearparameter system. In this paper, the stiffness and damping parameters of an engine mount system are obtained in experiments. The corresponding mass matrix and stiffness matrix are used for establishing the dynamic computation model of the engine mount system. The model is validated by relative analysis of operational modal and calculated modal. Results indicate that the computation model including dynamic stiffness parameters is more practical than the traditional model of static stiffness.
