Vibration mechanism analysis and dynamic model development of magnetically suspended rigid rotor system
摘要
Abstract
By the virtue of active magnetic bearing, magnetically suspended inertia actuators can make micro-vibration come true through active vibration control. However, there still exist vibrations with some frequencies in magnetically suspended inertia actuators. Firstly, the vibration mechanism of Magnet Runout is analyzed based on the analysis of rotor unbalance and Sensor Runout, then the dynamic model of the magnetically suspended rigid rotor system composing of three vibration sources is developed and divided into translational motion and torsional motion. The analysis dedicates that rotor unbalance, Magnet Runout and Sensor Runout will arise vibrations through different channels, and that the vibrations include the fundamental frequencies and their harmonics. Lastly, the requirements of active vibration control are proposed for the magnetically suspended rigid rotor system, and are useful for the future research.关键词
