With continual interest in expanding the performance envelope of engineering systems, nonlinear components are increasingly utilized in real-world applications. This causes the failure of wellestablished techniques to mitigate resonant vibrations. In particular, this holds for the linear tuned vibration absorber (LTVA), which requires an accurate tuning of its natural frequency to the resonant ...

The oscillations of tall slender towers under environmental loads are usually of large amplitude. In order to protect these structures, suitable absorbers can be installed to control or limit the amplitude of oscillation. In this paper, passive and hybrid control strategies are used to improve the dynamic response of a tall tower. A pendulum attached to the top of the tower is used as a vibrati...

Watts [1] in 1883 and Frahm [2] in 1909 reported on the first use of a dynamic vibration absorber. The range of industrial applications of such device is wide and includes the minimization of the rolling of ships, the damping of torsional vibration of internal combustion engines and the smoothing of vibrations in a barber cutter. The minimization of oscillations of tall buildings by means of dy...

Vibrational energy harvesting seeks to convert ambient energy into electricity when battery replacement or line transmission is infeasible or impracticable. Electromechanical mass-spring harvesters are designed to exhibit a resonance frequency close to the principal vibrational frequency of the main or environmental system; excited near to resonance, the harvesters convert the kinetic or potent...

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...
