抄録
This paper studies an efficient method of estimation of dynamic properties such as natural frequencies, modal damping coefficients and participation factors, of multiple degree of freedom linear system. The EK-WGI method which was previously proposed by the present authors is used for the solution of a system identification problem. To solve a multiple degree of freedom linear system, the modal analysis technique is corporated into the formulation of the state space equation. It is found that dynamic properties can be estimated even if an excitation and a single response time history at any point of mass are available. It is also found that if observed response at each mass are available for the identification, they can be used for the verification of estimated dynamic properties.
