On the numerical simulations of amplitude-adaptive impact dampers

Publication date: Available online 21 October 2019Source: Journal of Sound and VibrationAuthor(s): Tunc Yüzbasioglu, Jimmy Aramendiz, Alexander FidlinAbstractTwo impact dampers are analysed and compared with respect to their effectiveness for vibration reduction. Estimations of nonlinear system behaviour are derived using only well-known solutions for a linear dynamic vibration absorber. Critical parameter values separating domains with qualitatively different system behaviours are found. Using numerical simulations, the estimations are verified and the influence of each system parameter on the vibration amplitudes is investigated individually. Each of these systems exhibits advantages in the suppression of particular resonances, because they react either to the absolute or relative motion within the system.
