Centrifugal pendulum vibration absorber (CPVA) has been used as a torsional vibration suppression device. Recently, downsizing turbotechnology is widespread and it causes a torsional vibration in the drivetrains of automobiles, and CPVA is used for torsional vibration suppression. In such cases of vibration suppression of the drive-train shaft, it should be modeled as a multi degrees-of-freedom system and considered the suppression of its multiple modes. However, most of researches on CPVA so far have focused on a one degree-of-freedom system, and the vibration analysis and its suppression of the torsional vibration caused in the multi degrees-of-freedom system has been hardly investigated. In this paper, the dynamical characteristic of torsional vibration of the multi degrees-of-freedom system with CPVAs is investigated both theoretically and experimentally. Vibration suppression mechanism of CPVA on the torsional vibration of the multi degrees-of-freedom system is studied by the eigenvalue analysis. The vibration suppression effect of CPVA on the harmonic resonances, and the occurrence of superharmonic resonances in multiple modes are observed by the numerical simulation. Then, nonlinear theoretical analyses of harmonic resonances and superharmonic resonances are performed and the vibration suppression effects of CPVA are explained. These obtained theoretical results are confirmed by experiments.
