Generating Traveling Waves in Finite Media Using Single-Point Excitation via Passive Absorber
… or more attached spring-damper (SD) systems as passive absorbers is studied when excited by a harmonic force. The location of the spring-damper system divides the beam into two dynamic regions: one which exhibits non-reflecting traveling waves and the other with standing waves. In this work, the …

Adaptive tuned vibration absorber
… to a previously designed tunable vibration absorber. The adaptive vibration absorber is capable of detecting the frequency of the driving force and tuning itself automatically to that particular frequency. The primary structure was previously designed to obtain a certain natural frequency. …

The Control of Interior Cabin Noise Due to a Turbulent Boundary Layer Noise Excitation Using Smart Foam Elements
… of frequencies. The acoustic foam acts as a passive absorber and targets the high frequency content, while the PVDF serves as the active component and is used to overcome the limitations of the acoustic foam at low frequencies. The fuselage skin of an aircraft was represented by an …

Acoustic energy harvesting with emphasis on low frequencies
… operate as a harvester and the same time as a passive absorber. These test results further show that the output voltage of the proposed AEH can be adequate for charging a rechargeable battery or for driving an electronic load, while the electric power delivered to a load resistance may be up to …
