Abstract This paper proposes the application of resonator rings to reduce the amplitude of lateral vibrations of rotating machines. The resonator is composed of four beams attached to a rigid cylinder at the shaft position and a flexible ring at the other extremity. A continuous model, discretized by means of the finite element method, is considered with a shaft, one disk, two rigid bearings, and several resonator rings. The Campbell diagram and the response of the system in the frequency domain are analyzed. It turns out that the proposed resonator gives good results: the designed resonator is able to create a band gap around a target critical speed.

使用谐振环减少旋转机器的振动

摘要 本文提出了应用谐振环来降低旋转机械横向振动的幅值。谐振器由在轴位置连接到刚性圆柱体的四根梁和在另一端的柔性环组成。通过有限元方法离散化的连续模型被认为具有轴、一个圆盘、两个刚性轴承和几个谐振环。分析坎贝尔图和系统在频域中的响应。事实证明，所提出的谐振器提供了良好的结果：设计的谐振器能够在目标临界速度附近产生带隙。
