Recently, it is required to consider synthetically the dynamic characteristics of the spring-mass system from the standpoint of both vibration isolation and noise isolation. In the present paper, application of the finite element method is proposed in order to answer this request. Mass and stiffness matrices are derived by the use of exact solution of the coil spring in equilibrium. Calculated values using finite element approach agree well with experimental values, and dynamical characteristics of spring-mass system become clear for wide range of frequency.
