A method based on sensitivity analysis is presented for identifying the moment of inertia, spring constants and location of the center of gravity of a rigid body system supported by springs. This method is used to examine a technique for determining spring constants, spring locations and their arrangement so that the desired natural frequencies can be in tune. Further, the moment of inertia and the location of the center of gravity are identified from modal parameters measured in a vibration test model. The results of this investigation will be valuable in applications to vibration-proof-foundation design.
