| Abstract: | Taking one z-type retractable azimuthing thruster for DP system of 2000t Floating Crane as an example,this paper analyzes the structural characteristics of the z-type retractable azimuthing thruster shaft system.The torsion vibration model about its shafting line is built and the nature frequencies and mode shapes are calculated.Finally,the Mode-Superposition method is used to calculate the characteristics of forced torsion vibration,which validates the choice of super elastic coupling. |
