设计了用于转子振动控制的多层挤压型电流阻尼器，通过对悬臂转子系统的实验发现：随外加电压的增大，这种阻尼器能有效地抑制转子系统的临界共振，但当转速超过临界转速后，系统的响应反而增大，为消除这种不利影响，引入了开／关控制法，实验表明：它既能有效抑制临界共振，消除不利影响，又不会引起系统的不稳定。最后实验验证了这种阻尼器抑制转子系统突加不平衡响应的有效性。
The multi-layer squeeze type current damper for rotor vibration control is designed. The experiment of cantilever rotor system shows that with the increase of applied voltage, this kind of damper can effectively restrain the critical resonance of rotor system. However, When the critical speed is exceeded, the response of the system increases. To eliminate this adverse effect, an on / off control method is introduced. Experiments show that it can effectively suppress the critical resonance and eliminate the adverse effects without causing system instability . The final experiment verifies the effectiveness of this damper in suppressing sudden imbalance response of the rotor system.
