| 摘 要： | 结合电磁轴承的原理和结构以及旋转机械的减振理论，提出一种新型结构的支承。它将电磁轴承安装在主支承上，由主支承提供主刚度，而电磁执行器则根据需要提供附加的阻尼和刚度。对其被动式减振机理进行了研究，建立了恒压源式被动控制模型。其中支承中的电磁执行器利用直流电励磁，产生被动阻尼和刚度，阻尼值的大小由励磁电压的大小决定。该支承结构应用于实验转子系统，取得了较好的减振效果。

| Abstract: | A new kind of auxiliary electromagneticbearing was presented in this paper. It consists of themain bearing which provides the main rigidity and elec-tromagnetic bearing which makes use of the voltage orcurrent to produce the flux so as to generate the addition-al rigidity and damping. A passive control model of auxil-iary electromagnetic bearing with constant direct voltagewas set up and the vibration reduction principles werestudied. It can generate passive damping and rigidity bythe direct voltage and the value of the damping and rigidi-ty are determined by the voltage. It is used in a singledisk rotor system and good vibration reduction results areachieved. |
