中文摘要：
为了抑制转子系统的振动和研发高性能的转子系统振动主动控制执行元件，基于电涡流原理提出了一种新型的转子系统径向电涡流阻尼器，在一个带有双盘的柔性转子系统上详细地测量了不同磁场强度条件下径向电涡流阻尼器支撑的转子系统在非旋转状态下的传递函数、在恒定转速下的运动轨道以及在慢加速运行过程中的不平衡响应曲线，并进行了利用径向电涡流阻尼器对转子系统的振动进行分段和比例控制的有效性试验。结果表明了这种新型的径向电涡流阻尼器不仅具有结构简单、无需流体介质、无机械接触等特点，而且其动力特性还容易控制，在设计合理的条件下能够显著地减小转子系统的振动，是一种被动和主动兼备具有良好发展和应用前景的转子系统阻尼结构。
英文摘要：
In order to attenuate the vibration of rotor system and to develop actuator of active vibration control of rotor system with high-performance performance, a novel radial eddy current damper for rotor system was presented based on the eddy current principle. The frequency response functions of the rotor system supported on the radial eddy current damper in the stationary, the rotor motion orbits in the steady state rotational speeds and the unbalance response curves in the slowly accelerating operation were measured on a flexible rotor system with two disks at different magnetic flux densities, and the effectiveness of the on-off control and the proportional control on rotor vibration were also studied. It is shown that the radial eddy current damper not only has many advantages such as a simple structure, no working fluid, no contact, but also the dynamic behavior of the radial eddy cur- rent damper is easily controlled by the application of a magnetic field, the radial eddy current damper can significantly suppress the vibration of the rotor system for properly designed case. The radial eddy current damper can be used as passive or active actuator in the rotor system.
