ABSTRACT
This chapter presents the fundamentals of the method for the dynamic characterization of Resilient Mounting Elements (RME) through the experimental measurement of their Dynamic Transfer Stiffness. It examines the problem definition is given making reference to the one-dimensional approach and the theoretical background, which is based on the hypothesis of the independent single-point-connected system. The simplified approach to measure the dynamic stiffness of a RME is based on the assumption of treating the problem as a one-dimensional problem in which the structure-borne noise prediction is carried out by considering independent from each other all the transmission paths through the single resilient mounting. The typical transmissibility curve of a marine diesel engine resilient mounting is represented in narrow band on a log-log scale. The excitation mass function is to provide the condition of contact point at the input side of the resilient mounting and, as the blocking mass, it is dynamically decoupled from the test rig structure using auxiliary isolators.
