Abstract

Drive system is the main vibration source of the ship.Nowadays,vibration analysis of the ship's drive system is focused on the torsional vibration of the shaft system without considering the effect of the structural vibration.In this paper,the finite element model for a vibration-test table of the ship drive system is established and analyzed by means of the ANSYS software.Comparing the computation results with the experimental data,the reliability of the finite element method is verified.By changing the condition of vibration excitation,the vibration translation law of the ship's drive system is studied.
