为了提高双框架磁悬浮控制动量陀螺（DGMSCMG）的位移刚度和降低功耗，研究了一种新型轴向被动磁轴承（APMB）结构。与现有的APMB不同，该APMB由分段永磁体和磁环组成。基于端部磁通量，采用等效磁路法和微元法推导了位移刚度和角刚度的表达式。分析了气隙长度、永磁体长度、永磁体高度、磁环端部长度等结构参数与刚度的关系。此外，提出了APMB轴向位移刚度的测量方法，验证了理论方法的正确性。制作了DGMSCMG样机并进行了减速特性实验，实验结果反映了APMB的低功耗特性。
To increase the displacement stiffness and decrease power loss of double gimbals magnetically suspended control momentum gyro (DGMSCMG), this paper researches a new structure of axial passive magnetic bearing (APMB). Different from the existing APMB, the proposed APMB is composed of segmented permanent magnets and magnetic rings. The displacement stiffness and angular stiffness expressions are derived by equivalent magnetic circuit method and infinitesimal method based on the end magnetic flux. The relationships are analyzed between stiffness and structure parameters such as length of air gap, length of permanent magnet, height of permanent magnet and end length of magnetic ring. Besides, the axial displacement stiffness measurement method of the APMB is proposed, and it verified the correctness of proposed theoretical method. The DGMSCMG prototype is manufactured and the slow-down characteristic experiment is carried out, and the experimental result reflects the low power loss feature of the APMB.
