Adaptronic Vibration Absorber for a Wide Field of Applications

Keywords: adaptronic, active materials, auxiliary mass damper, dynamic vibration absorber, vibration damping

Unwanted externally excited or self-induced vibrations occurring in many mechanical structures of our engineered environment need to be reduced in the interest of lower environmental impact and increased structural durability. Reducing vibrations can be achieved with the help of passive vibration absorbers which extract kinetic energy from the vibrating host system or active ones which introduce opposing forces into the structure to affect compensation. Focusing on an auxiliary mass damper, this paper shows how both classes of absorber can be unified in a single, compact unit through active materials and an adaptronic system approach. Simulation and experimental results corresponding to a particular technical application illustrate broadband damping of time varying frequency components in the spectrum of structural vibrations.
