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.
