Aiming at the problem that the vibration characteristic of marine shaft system was influenced greatly by bearing displacement, the finite element rotor dynamics method was proposed to calculate the influence of bearing displacement on vibration characteristic of marine shaft system. Firstly, finite element model was established in ANSYS by taking a test bench as the study object, and the vibration characteristic of shaft system in linear state and bearing displacement state was calculated respectively by using finite element rotor dynamics method. Furthermore, the vibration characteristic of shaft system test bench in linear state and bearing displacement state were measured respectively. Results show that the vibration response of both calculating and measuring coincides basically.
