Numerical solutions for optimal double-mass dynamic vibration absorbers attached to a damped primary system

Mechanical Engineering Journal, 2020
Because double-mass dynamic vibration absorbers (DVAs) are superior to single-mass DVAs in terms of their vibration suppression performance and robustness, they have been increasingly studied recently.

Optimal design of a series-type double-mass hysteretically damped dynamic vibration absorber based on the stability criterion

Mechanical Engineering Journal, 2021
In most dynamic vibration absorbers (DVAs) used in practical applications, polymeric materials that have both restoring capabilities and damping effects are used instead of coil springs as spring elements.

The Stability Analysis of a Vibrating Auto-Parametric Dynamical System Near Resonance

Applied Sciences, 2022
This paper examines a new vibrating dynamical motion of a novel auto-parametric system with three degrees of freedom. It consists of a damped Duffing oscillator as a primary system attached to a damped spring pendulum as a secondary system.

Decentralized Model-Reference Adaptive Control Based Algorithm for Power Systems Inter-Area Oscillation Damping

Energies, 2022
Being the primary cause of inter-area oscillations and due to the fact that they limit the generation’s output, Low-Frequency Electromechanical Oscillations (LFEOs) represent a real threat to power system networks.
