摘要

摘要: 对调谐质量阻尼器在旋转机械振动控制中的应用进行了研究,不改变原有转子系统支撑形式,设计了一种半主动笼式调谐质量阻尼器.提出基于转速的分段开关控制策略,并开发了一套基于laborary virtual instrument engineering workbench(LabVIEW)的转子振动实时闭环控制系统,可根据转速对该笼式调谐质量阻尼器通过变质量实现在线动态调节自振频率,实现半主动控制.搭建了单跨转子调谐质量阻尼实验台装置,对转子过临界转速的振动进行了实验研究.结果表明:基于开关控制的半主动笼式调谐质量阻尼器能有效降低转子过临界振动,减振幅度可达83.4%,并能很好避免调谐质量阻尼器引起的新的共振峰.

Abstract: An application of tuned mass damper (TMD) in the semi-active vibration control of rotor system was proposed,which also had been studied. And a kind of semi-active cage-type tuned mass damper was designed without changing original supports of the rotor system. The section switch control technique based on the rotor speed was put forward.Based on laborary virtual instrument engineering workbench (LabVIEW), a closed loop system for the natural frequency regulation was developed for semi-active vibration reduction in which cage-type TMD was adjustable according to different rotor speeds. The single span rotor TMD test rig was built and the experimental study has been carried out. Experimental results show that rotor vibration is well controlled with the section switch control technique of the semi-active cage-type TMD when the rotor goes through the critical speed, the vibration damping effect reaching up to 83.4%, which helping to avoid the extra resonance peak caused by TMD.
