On the experimental characterization of resilient mounting elements

The results of an experimental campaign aimed to the dynamic characterization of a typical resilient mounting element are presented, showing the force of the applied approach and the aptitude of the testing devices available at the Ship Noise and Vibration Laboratory (NVL) of the University of Trieste. The paper presents the fundamentals of the method for the dynamic characterization of Resilient Mounting Elements (RME) through the experimental measurement of their Dynamic Transfer Stiffness (DTS). In the paper, the problem definition is given making reference to the one-dimensional approach and the theoretical background is introduced, which is based on the hypothesis of the independent single-point-connected system. Then the experimental method is introduced by recalling the ISO 10846 standard, and a description is given of the facilities available at the NVL. Finally, the results of the test campaign are discussed.
