摘要

为了评价内嵌式黏性流体单元自适应减振方法(IVFUM)消减运动柔性结构残余振动的效果

进行了内嵌黏性流体欧拉梁在旋转态下的自适应减振试验

并对试验所测试的残余振动衰减信号进行了处理.针对旋转态下内嵌黏性流体欧拉梁残余振动信号具有刚体衰减转动的慢变信号与柔性结构残余振动快变信号相耦合的特征

提出一种简明、实用和精度良好的减振效果评价体系——单自由度等效阻尼比法

结合非线性最小二乘法对信号进行处理

并编制了相应的程序.信号分析结果可有效地评价结构内嵌黏性流体方式对运动的工程柔性欧拉梁残余振动的减振效果.

Abstract

In order to evaluate the effect of vibration suppression of the interior inlay viscous fluid unit method(IVFUM)

a self-adaptive remnant vibration suppression experiment for the rotating interior inlay viscous fluid Euler beam was carried out

and the remnant vibration attenuation signal was processed. Considering that the case studied is characterized by coupled slowly varying signal of rigid body attenuated rotation and quickly varying signal of flexible structure remnant vibration

an evaluation system named SDOF(Single Degree of Freedom)equivalent damping ratio method regarding vibration suppression effect was presented to process the vibration signal via nonlinear least square method

and the corresponding program was coded. The analytical results efficiently evaluated the remnant vibration suppression effect of the rotating flexible Euler beam with interior inlay viscous fluid.
