摘要
This paper investigates suppression of vibrations in 2dof forced linear system with a nonlinear energy sink (NES) attached. Ability of the properly tuned single NES to successfully absorb energy from both excited modes of the linear subsystem is demonstrated. The proposed methodology of the NES tuning is based on the results of analytic treatment. The strongly nonlinear vibration absorber is compared to the best-tuned linear one and excitation zones of preference of the nonlinear absorber are revealed.
