| Abstract: | The vibration problem of double-deck isolation system under random excitation is studied in the paper. The analytical expressions of the mean square value of the absolute accelations and relative displacements at the mass points of two degrees of freedom system are derived. The relationship between the structural parameters and the system response is illustrated by relation curves and then the identification method of the structural parameters of double-deck isolation system is presented. |
