Naval vessel machinery mounting technology and its recent advances

Machinery mounting system is one of the most important vibration and noise attenuation technology of naval vessels.There are numerous papers relative to naval vessel mounting technology,but papers which systematically discuss the characteristics,application and advances,especially recent domestic advances of this technology are rather scarce.By focusing on the vessel mounting technology whose effectiveness has been verified by engineering practice,the development history of this technology is summarized firstly.The characteristics of simple mounting,two-stage mounting, raft mounting and air spring mounting are analyzed,followed by the introduction of recent advances including intelligent air spring mounting,highly effective propulsion machinery mounting,active/passive hybrid mounting and thrust bearing mounting.Finally the development trend of mounting technology is discussed.A general view of the development of naval vessel machinery mounting technology is presented and can be used as a reference for naval vessel noise attenuation research and engineering design.
