| 英文摘要: |
| Base excitation is one of common excitations in rotor system. In order to study the dynamic characteristics of rotor systems under base excitation and the effect of integral squeeze film dampers (ISFDs) on their dynamic characteristics, a single-disk rotor test rig, where mass imbalance and base excitation could be applied, is developed.Experimental research on the rotor system response under sinusoidal base excitation conditions with different frequencies and excitation forces is performed and the effect of ISFD on the dynamic characteristics of the rotor is investigated. The experimental results demonstrate that when the sinusoidal base excitation frequency approaches the first critical speed of the rotor system or the natural frequency of the rotor system base, strong vibration occurs in the rotor, indicating that the base excitation of the two frequencies has a greater impact on rotor system response. In addition, with the increase of the base excitation force, the vibration of the rotor will be increased. ISFDs can significantly inhibit the vibration due to unbalanced forces and sinusoidal base excitation in rotor systems. To a certain extent, ISFDs can improve the effect of sinusoidal base excitation with most frequencies on rotor system response, and they have a good vibration reduction effect for sinusoidal base excitation with different excitation forces. |
