| Abstract: | The transfer matrix method is adopted in the paper to calculate the critical speeds, the unbalance response and the initial curve resoponse of the rotor case system. The elastic energy distributions for stable responses of the system at the critical speeds are obtained. A method is presented to determine the behavior of the critical speeds by making use of the energy distribution between the rotor and the case. And influence of the case on vibration behaviors of the system is studied.ZK)〗 |
