摘要

以小型航空发动机的转子和支承结构为设计参考

设计和制造了一种支承在挤压式磁流变液阻尼器上的单盘转子系统

并试验研究了在不同控制电流条件下系统的不平衡响应特性。试验发现

磁拉力对一阶临界转速和临界振幅的影响可以忽略;油膜反力可降低转子系统在无阻尼临界转速处的振幅

并使临界转速增加。根据这一特性

提出用开关控制能使阻尼器具有最佳的减振效果。研究表明

挤压式磁流变液阻尼器具有结构简单、控振效果明显、反馈迅速等特点

在高速柔性转子系统的振动控制中极具应用前景。

Abstract

Refer to the rotor and supporting structure of small aero-engines

a single-disk rotor system supported on a squeeze MR fluid damper was designed and manufactured.The unbalance response of the system at different control currents was experimentally studied.It was found that the effects of the magnetic pulling force on the first critical speed and the amplitude can be omitted.The oil film reaction force can diminish the amplitude at the critical speeds without damper

and increase the critical speeds.The damper will have the best effect in minimizing the vibration within the specified range at all working speed by using on-off control method.The research shows that the squeeze MR fluid damper has the advantages such as structure simplicity

high effectiveness

quick response

etc.

and this kind of damper has a promising potential future in vibration control of high-speed flexible rotor systems.
