| Abstract: | A dynamics model and its corresponding mathematics model of the drive system of the enging is set up,and the model is solved through using Riccati transmits matrix.A dangerous mode in torsional vibration is found through a calculation of flexible degree of modality,then the weak links of this system are confirmed through a calculation of distributing rate of energy under this dangerous mode,it offers a theoretic evidence for the optimizing design of the drive system and shows an improved direction for the project. |

| Keywords: | transfer matrix flexible degree of modality dangerous mode energy distribution |
