Nonlinear Response of a Roller Chain to Combined Forcing and Parametric Excitations : 4th Report. Experiment of 1/3-Harmonic and Parametric Combination Resonance-No. 2

Abstract

This paper shows the comparison of the experimental and the analytical results of the 1/3-harmonic and parametric combination resonance generating in a chain system treated in the previous report. The influence of a phase angle between the forced displacement and the prescribed tension fluctuation upon the 1/3-harmonic and parametric combination resonance are examined in the experiment using a chain with small friction. As the friction decreases, the characteristics of the combination resonances become complicated and develop many stable branches. The characteristics and the 1/3-harmonic vibration are also compared with each other. A fine agreement between experimental and analytical results was confirmed.
