Abstract: In this paper, the stiffness matrix of the dynamic equation of the object is established. basis on the equivalent stiffness matrix of the elastic substrate compated by finite element method at first. Furthermore, the dynamic equation under the physic coordinate of the object is established and solved.

Key words: finite element method, equivalent stiffness matrix, equation
