This paper is based on the multi-body dynamic coupling theory and finite element theory. A multi-body dynamic coupling model of the large-scale vessel is built and the torsion vibration characteristics of slow-speed ship propulsion shafting are analyzed. The measurements of shafting torsional vibration in the real ship are compared with the results from the simulation model. Then, the differences between measurements and simulation results are analyzed in multi-orders. The analysis result indicates that the simulation results are almost the same with measurements obtained from the real ship, which verify the correctness and feasibility of the model. At the same time, the influence of ship hull deformation on the torsion vibration of ship propulsion shafting is discussed by Adams/Vibration. The analysis shows that the ship hull deformation could cause the significant increase of torsional vibration of ship propulsion shafting.
