Parameters such as the principal moment of inertia, the principal axis of inertia, location of center of gravity are very necessary for simulation of the dynamic properties for the design of a mechanical system. Usually some of these inertial properties are identified by the pendulum method, which is an experimental procedure to obtain these parameters from the period of the suspended specimen using the principle of a pendulum. However, as the specimen becomes more complex in shape or heavier, the resulting parameters are identified with poorer accuracy, because the accuracy for location of the center of gravity decreases. Therefore, the authors examine an approach for experimental identification of the characteristic matrices, i.e., the mass, the damping and the stiffness matrices, with using the modal parameters obtained by modal testing applied to obtain the inertial properties for resiliently supported mechanical system. From these results, it is shown that this approach is available for obtaining the inertial properties of mechanical systems.
