Abstract

This study proposes a dual-coil magnetorheological torsional vibration damper (MRTVD) and verifies the effectiveness of semi-active damping control to suppress the shaft system's torsional vibration via experimental research. Firstly, the mechanical model of the designed MRTVD and its coupling mechanical model with the rotating shaft system are established. Secondly, the torsional response of the shaft system is obtained via resonance experiments, and the influence of the current on the torsional characteristics of the magnetorheological torsional damper is analyzed. Finally, the MRTVD is controlled using the skyhook control approach. The experimental results demonstrate that when the main shaft passes through the critical speed range at various accelerations, the amplitude of the shaft's torsional vibration decreases by more than 15%, and the amplitude of the shaft's torsional angular acceleration decreases by more than 22%. These conclusions validate the inhibitory effect of MRTVD on the main shaft's torsional vibrations under skyhook control.

摘要

本研究提出了一种双线圈磁流变扭转振动阻尼器（MRTVD），并通过实验研究验证了半主动阻尼控制抑制轴系扭转振动的有效性。首先，建立了所设计的MRTVD的力学模型及其与旋转轴系的耦合力学模型。其次，通过共振实验获得轴系的扭转响应，并分析电流对磁流变扭转阻尼器扭转特性的影响。最后，采用天钩控制方法对MRTVD进行控制。实验结果表明，当主轴在不同加速度下通过临界转速范围时，轴的扭转振动幅值降低超过15%，轴的扭转角加速度幅值降低超过22%。这些结论验证了在天钩控制下MRTVD对主轴扭转振动的抑制作用。
