Abstract

This paper describes the results of analytical and experimental investigations of the nonlinear harmonic and parametric resonance phenomena of a roller chain stretched vertically which is regarded as a system with many degrees of freedom, when the elongation of the chain during vibration is taken into account. The resonance treated in this report is one of the resonances excited under combined forcing and parametric excitations in which the ratio of the forced lateral displacement acting at a lower end to that of the tension fluctuation is 1:2. Two chains with different frictional coefficients were used in experiments in order to examine the effect of friction upon the vibration characteristics. The experimental results showed remarkable features attributable to the combined excitations and agreed well with the analytical results.
