摘要：
Based on the theory of elastic wave in structure, through the established longitudinal vibration model of the shafting which takes thrust bearing and its supporting system as one boundary condition, the frequency characteristic equation of longitudinal vibration was derived and the first-order natural frequency with Taylor series was estimated. Then combined with a certain ship parameters, the comparative research on the isolation effect of shafting longitudinal vibration between Integrated Vibration Isolator and Resonance Charger was put. The results show that the effect of Integrated Vibration Isolator could be better in large frequency bands, while RC more performance characteristics of DVA; furthermore, on the basis of safety operation of the shafting, larger damping frequency bands could be acquired with more weight of Integrated Vibration Isolator and less of RC. © 2017, Editorial Board of Journal of Ship Mechanics.
