| 摘 要： | 实验研究了一种剪切式磁流变流阻尼器在转子振控制中的应用，实验发现，磁流变液阻尼器的刚度和阻尼随施工磁场强度的增加而增大；支承在磁流变液阻尼器上的转子系统的振幅在亚临界区及临界转速处随施加的磁场强度的增加而减小，而在超临界区则随磁场强度的增加而增大；系统的临界转速随磁场强度的增加而升高，通过简单的开关控制，可使转子的振动在全转速区的内达到最小。

| Abstract: | The stiffness and damping of the MR damper are increased with the magnetic field strength increase, and the vibration amplitude of the rotor system supported by the MR damper is decreased at subcritical and critical speeds, and is increased at supercritical speed. The critical speed of the rotor system is increased with the increase of the applied magnetic field. The rotor vibration can be minimized within the range of all working speed by using simple on/off control method. |
