Study on the Structure-borne Sound Transmission of a Machine through Rubber Mounts

Machines on board a ship are mounted on decks and transmit its structure-borne sound to the deck through resilient mounts. To predict the ship noise generated by the structure-borne sound of the machine, It is necessary to estimate the vibration level of the base structure. In this paper, a simple dynamic model is considered for vibration isolation systems consisting of a source, an isolator, and a base structure. The high frequency mobilities of the simple base structure are reviewed and wave effects in the mount are discussed in relation to isolation performance.
