Simulation Study on Blade Frequency Vibration Control for a Vertical Magnetic Levitation Agitator

针对搅拌机叶轮悬伸较长,叶轮受到周期干扰时会严重影响磁悬浮搅拌器转子的稳定运行的问题,研究一种相移陷波滤波器叶频振动控制,探讨了相位补偿角的有效性,建立了立式磁悬浮搅拌器转子动力学模型,并基于MATLAB软件搭建了仿真模型,验证了所提振动控制算法的效果及有效性。

The long overhang of the agitator impeller can lead to periodic interference,significantly affecting the stable operation of the magnetic levitation agitator rotor.Therefore,the study of the control methods for agitator blade frequency vibration is crucial to ensure the device’s smooth operation.To mitigate the impact of blade frequency vibration,we explored the use of a phase shifted notch filter for vibration control,and investigated the effectiveness of the phase compensation angle.A rotor dynamics model of a vertical magnetic levitation mixer was established,and a simulation model was created using MATLAB software to validate the efficacy and robustness of the proposed vibration control algorithm.
