Vibration attenuation and generation using DEAP technology
The PhD project indicates a potential for DEAP transducers within AVC. The PolyPower transducers are found to be most effective for reducing vibrations in applications with low vibration frequency (1-100 Hz) and relatively high amplitude (1-10 mm).
The above characteristics correspond to vibrations from machinery in construction and production areas, in vehicles, in helicopters fuselage due to main rotors, and in air conditioning systems, to mention a few.
Moreover, the DEAP transducers are also found to be suitable for generating vibratory motions in the range of 40-400 Hz and 1-10 mm. Such cyclic motions are desired in products like pumps, loudspeaker used for alarm purposes, haptic interface devices, fitness and massage vibratory units, industrial mixers, and anti speckle systems.
Applying DEAP for active vibration control
The PhD project examined the material characteristics, actuator design and real time system operation to be able to evaluate the potential of the DEAP transducers for AVC. During the project, the suitability of DEAP for application within AVC was examined and documented.
It has been observed that the unique characteristics of PolyPower DEAP such as its elastic nature and metallic electrodes provide unique optimization opportunities. These optimization possibilities can be used for designing highly efficient DEAP transducers for specific products within AVC.
Using PolyPower DEAP transducers for AVC is an interesting application area that hold promising potential. If you want to know more about the outcome of the PhD project or discuss potential AVC applications, please contact Danfoss PolyPower A/S at email@example.com
