The longitudinal vibration characteristics and parametric analysis of a ship thrust bearing integrated with internal disc springs

To reduce the transmission of shafting longitudinal vibration in surface ships, a design thrust bearing integrated with internal disc springs is proposed and characteristics are studied. According to structural deformation springs, specific size combination forms designed, effective schemes achieved according static dynamic requirements. With integration into bearing, peak displacement response at base can be reduced by 10 dB two springs. The effectively suppress shaft hull, which has engineering significance for control ship.
