| Abstract: | By propeller blades and ice interaction, the excitation function is established. By electromechanical coupling vibration mathematical model, the electromechanical coupling dynamic equation is derived. It is used to study the effects on motor electromagnetic excitation force torsional vibration. Ice loads excitation force and the electromagnetic excitation force is used for torsional vibration analysis with 3500T the research ship. Study on Ice-propeller interaction force and the electromagnetic excitation are very important for low noise design of the electric propulsion shafting. |
| Keywords: | electric propulsion ice navigation hydrodynamic torsional vibration |
