为了测量径向混合磁轴承的当前刚度和位移刚度，提出了一种磁悬浮飞轮刚度测量新方法。首先，采用磁路法和有限元法对径向混合磁轴承的悬浮力和刚度特性进行了研究。其次，提出了一种径向混合磁轴承刚度的详细测量方法。它有两个程序：一是确定转子重力分别为+X（或+Y）方向和-X（或-Y）方向时转子位移与相应电流的关系，二是根据转子位移与电流的关系计算磁悬浮轴承的电流刚度和位移刚度。研制了三台角力矩为15 Nm的磁悬浮轴承样机，主要由两个轴向混合磁轴承和一个径向混合磁轴承组成。样机实验验证了所提出的径向混合磁轴承刚度测量方法的有效性。
To measure the current stiffness and displacement stiffness of a radial hybrid magnetic bearing, a new stiffness measurement method is proposed for a magnetically suspended flywheel (MSFW). Firstly, the suspension force and stiffness characteristics of the radial hybrid magnetic bearing are studied using magnetic circuit method and finite element method. Secondly, a detailed stiffness measurement method for a radial hybrid magnetic bearing is proposed. It has two procedures: one is the determination of the relationship between the rotor displacement and the corresponding current when the gravity of the rotor is in the +X (or +Y) direction and −X (or −Y) direction respectively, and the other is the calculation of the current stiffness and the displacement stiffness of the radial hybrid magnetic bearing in an MSFW according to the relationship between the rotor displacement and the current. Three prototype MSFWs with angular moments of 15 Nms are manufactured, and they mainly consist of two axial hybrid magnetic bearings and one radial hybrid magnetic bearing. The proposed stiffness measurement method of the radial hybrid magnetic bearing is verified by all prototype experiments.
