Aiming at the vibration control problem of ship propeller-shaft system, this paper put forward a design approach of ship propeller-shaft longitudinal two-stage vibration isolation system and its dynamic characteristics are studied. The vibration mathematical model of ship propeller-shaft longitudinal two-stage vibration isolation system is established. The influence of mass ratio, stiffness ratio and damping ratio of two-stage vibration isolation system is studied. The design is optimized taking a ship propeller-shaft system as an example. The results show that the ship propeller-shaft longitudinal two-stage vibration isolation system which is optimized has better isolation effect than the single-stage vibration isolation system. The research results have important reference value for ship propeller-shaft longitudinal vibration isolation design.
