| Abstract: | In this paper, the equivalent torsion vibration model is built of the CODAD propulsion system. Considering the variable characteristics of the Geislinger coupling, the free torsion vibration and the force torsion vibration of the shaft are calculated and analyzed. The result can tell that the variable characteristics are too important to be neglected. Besides, the model and calculation are verified by the test on-board. |
