The increase of the propulsion power of the ship and the increase of the distance between the two adjacent bearings lead to the reduction of the fatigue life of the shaft system. The research on the fatigue life of the ship propulsion shaft system has important theoretical significance and practical engineering application value for the ship design. Based on the ANSYS Workbench platform, this paper builds the physical model of the coupling part of the bending and torsion, obtains the transient analysis result under the working speed, and introduces it into ANSYS Ncode for fatigue analysis under flexural and torsional coupling.
