This paper presents a time domain method to identify the mass, stiffness and damping parameters of a mechanical structure. First, the characteristic matrix of the structure system is obtained from the modal parameters of the structure. Secondly, the mass parameters are determined from the autocorrelation function of the measured responses and the ones calculated from modal parameters. Consequently, the stiffness and damping parameters are obtained from the characteristic matrix and mass parameters. Finally, two simulation examples, of which one is a five degree-of-freedom model including a rotation mode, are demonstrated in detail with figures and tables. The results are in good agreement with the analytical ones.
