Violent hydrodynamic loads due to ventilation and strongly oblique inflow are believed to be important mechanisms that influence propeller shaft dynamic forces and moments and therefore also the mechanical design of the drive train and it's components such as bearings and bevel gears in azimuthing thrusters. However, the resulting mechanical responses in the drive train are a result of a combination of hydrodynamic loads on the propeller, the dynamics of the drive train and the propulsion motor. To analyse the drive train as a dynamic system, Multi-Body Simulation is applied. This paper describes a simulation model that provides the instantaneous propeller thrust and torque as a function of instantaneous submergence, propeller speed and ship velocity. This simulation model is intended to be integrated with the rest of the Multi-Body Simulation model. The output of the simulation model is compared with experimental results, and a fairly good agreement is found. Several areas that need refinement are identified.
