In the paper, analysis procedures and design concepts for the selection of resilient mountings for marine diesel engines are reviewed. 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 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. A comparative study carried out on two different configurations of a resilient element designed by Vulkan Italia Srl to be used as vibration isolator for medium-speed marine diesel engines is finally discussed.

Abstract
In the paper, analysis procedures and design concepts for the selection of resilient mountings for marine diesel engines are reviewed. 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 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. A comparative study carried out on two different configurations of a resilient element designed by Vulkan Italia Srl to be used as vibration isolator for medium-speed marine diesel engines is finally discussed.Pubblicazioni consigliate
