| Abstract: | In the present paper, the damped system which takes into account both viscous damping and structural damping is defined as the synthetic damped system. The modal analysis of themulti-degree-of-freedom proportional synthetic damped system is discussed. The representation for the transfer function matrix is derived. By the relationship of Laplace transform and Z-transform, the ARMA time series model for this system is obtained. |
