摘要

Ship manufacturers invest considerable effort and money in improving the attenuation of noise radiated by ship into the water. A number of different noise sources contribute to the total acoustic signature on a ship. This dissertation focuses on the problem associated with low order harmonics generated by the diesel engines, transmitted through the engine mounts into the hull, and subsequently radiating into the water. The main intention of the work described here is to experimentally and numerically investigate the use of MR dampers to minimize the vibratory energy of the low speed diesel engine transmitted to the hull. Moreover, properties and control strategies are also investigated to develop a fundamental understanding of MR dampers for the purpose of designing and implementing these
