Abstract Based on static characteristics study of two quasi-zero-stiffness (QZS) isolators, effects of the two isolator models’ structural parameters on displacement range of low dynamic stiffness were contrastively analyzed.The dynamic model for longitudinal vibration of ship propulsion shafting based on QSZ isolator with its restoring force taken as one end’s boundary condition was established using the finite element (FE) method.The force transmissibility of the system was solved with the harmonic balance method.Combined with simulated ship working condition parameters, vibration isolation effects under excitation of blade frequency for ship propulsion shafting based on different isolator models were contrastively studied.Analysis results showed that the QZS isolator can realize longitudinal vibration reduction of ship propulsion shafting under excitation of blade frequency based on an equivalent linear system; choosing a suitable QZS isolator model and damping can avoid jump phenomenon occurring during main resonance and keep low frequency vibration isolation effect.
