It is significant to minimize marine vessel noise radiation by using resonance changer, and to reduce the longitudinal vibration of the propeller-shafting system. Firstly, this paper introduces the causes of the longitudinal vibration in marine vessel and early solutions to the problem. Then the history of resonance changer used in thrust bearing is reviewed. This paper is concerned with the theoretical analysis of resonance changer abroad and the optimization of resonance changer. The domestic research status of resonance changer is briefly discussed. A general view of the development of resonance changer is presented and can be used as a reference for naval noise attenuation research design.
