摘要
磁悬浮技术应用于机电陀螺直接改善了陀螺输出轴的支撑环境,消除了浮子组件与陀螺壳体间的机械接触,稳定了浮子质心位置,进而大幅度提高了液浮陀螺精度,优良的磁悬浮技术可使陀螺仪输出轴上的干扰力矩降低10倍以上。三浮陀螺磁悬浮技术分为有源磁悬浮和无源磁悬浮两类,文章在介绍磁悬浮系统的基础上,较为完整地介绍了三浮陀螺及其磁悬浮系统的发展历程。
The application of magnetic suspension technology in electromechanical gyroscope can improves its accuracy greatly, by improving the supporting environment of its output axis directly, eliminating mechanical contact between float assembly and gyro shell,stabling float centurion. Excellent magnetic levitation technology can reduce the interference torque on the output axis of gyroscope by more than 10 times. Magnetic technology of three-floated gyroscope can be divided into active and passive magnetic suspension. Based on the general introduction of magnetic suspension system, the development history of three-floated gyroscope and its magnetic suspension system is introduced in this paper.
