Abstract Parametric excitation in the pitch/roll degrees of freedom (DoFs) can induce dynamic instability floating cylinder-type structures such as spar buoys, offshore wind or wave energy converters. At certain frequency and amplitude ranges input waves, parametric coupling between heave DoFs results undesirable large rotational motion. One possible remedy to mitigate existence resonance is us...

Recently, a large amount of studies have been related to nonlinear systems with multi-degrees of freedom as well as continuous systems. The purpose of this paper is to optimize passive vibration absorbers in linear and nonlinear states for an Euler-Bernoulli beam with a nonlinear vibratory behavior under concentrated moving load. The goal parameter in the optimization is maximum deflection of t...

This paper examines a set of parametric tunings for vibration absorbers to enhance stability in the event simultaneous chatter during machining and proposes novel tuning criterion minimizing definite integral frequency response function, while accounting damping absorber’s base component. Chatter vibrations are an inherent characteristic processes, common tool mitigating is tuned mass damper (T...
