Abstract

A large flexible beam with a tip mass-pendulum system has been proven to be effective vibration-absorbing device for large flexible structures with tip appendages. In this study, the technique of digital image processing is used to demonstrate how unique experimental results can be obtained by the use of high performance data acquisition and high speed cameras. The measurements include time history records, frequency response curves, FFT and phase planes for beam and pendulum. The experiments were conducted in the neighborhood of the autoparametric region. The characteristics of the absorption region are analyzed and discussed. Experimental results obtained from image processing were used as input to the inverse problem. An inverse problem algorithm based on Levenberg-Marquardt formulation system parameters such as pendulum mass, length and viscous damping are determined. The results reveal that the use of digital image processing combined with inverse problem can be a novel method for system identification.
