Abstract
Using image processing and analysis, the dynamic behavior of the beam-free-pendulum system under low and high sinusoidal excitation was investigated. The system responses were investigated experimentally in the neighborhood of primary resonance condition. The results exhibited autoparametric interaction between the beam and the free pendulum when the primary resonance condition was satisfied. Experiments were conducted for two different pendulum weights under two different shaker forcing amplitudes, and the results were compared. Experimental data were obtained by sweeping between the frequencies that contain the resonance condition under investigation. The results of experiments for different beam-tip mass and pendulum mass ratios indicate that more powerful absorption action can be achieved when the smaller mass ratios are used.
