For the optimum design of a vibration isolation system which consists of a rigid body and elastic mounts, it is important to know accurately the design Parameters (i. e., mass, the location of the center of gravity, the moment of inertia, the principal axis of inertia of the rigid body, and the spring constant and location of the support of the elastic mounts) . In this paper, the authors propose a method of direct identification of these design parameters using sensitivity analysis and experimental data. The outline of this method is as follows : first, a vibration model is set up and eigenvalue and sensitivity analyses are carried out, and then the modal parameters are repeatedly modified by changing the design parameters appropriately based on the sensitivity values in order to correspond to the experimental data. A rigid body model and a compressor mount system are examined to verify the usefulness of this method. Furthermore, a design modification for a compressor mount system is applied by changing the location of the supports and tuning the natural frequencies of the vibration system in order to avoid resonance.
