Abstract: Systems and devices for dynamic damping of vibrations are described. Traditional methods of vibration damping often involve trade-offs between stiffness and damping, potentially compromising structural integrity for increased damping. The performance of these damping techniques can also be influenced by the specific profile of the vibrational excitation, presenting challenges in ensuring consistent and reliable damping across different operating conditions. A tunable friction-damping device formed from concentric layers can overcome many of these limitations and presents methods for dynamic damping of vibrations as an alternative solution.
