Abstract

In the paper, after a description of the theoretical basis for studying resilient mounting systems, an overview is given of approaches for their dynamic characterization by means of laboratory tests, which are performed by implementing the procedures given in the ISO 10846 standard. The facilities of the Ship Noise and Vibration Laboratory (NVL) of the University of Trieste are then presented. The procedure for carrying out the experi-mental test has been applied in order to achieve the dynamic response of a very large resilient mounting specifically designed for a medium-speed marine diesel engine. In the experimental campaign particular atten-tion has been paid to the checks performed to obtain effective results. The tests hereinafter presented allow to measure the dynamic response of the resilient element in the audio-frequency range, in both the vertical and horizontal directions. Outcomes of the experimental campaign are finally presented and discussed.
