Abstract
A digital twin of a marine propeller shaft is formulated. A method is proposed for predictive diagnostics on the basis of simulation. The simulation of a ship’s propeller shaft is considered. The shaft undergoes modal and static analysis. The reactive forces in the bearings and the stress and strain in the shaft are determined. The form and frequency of the structure’s intrinsic vibrations are derived. On that basis, the state of the shaft may be assessed, with or without load. Calculations of the mechanism’s reliability and durability are also possible by that means. The mathematical model may be used to monitor the load on the shaft so as to prevent damage to the system by fatigue failure.
