Elastomeric dielectric material has recently become a
\r\nnew alternative for actuator technology. The characteristics of
\r\ndielectric elastomers placed between two electrodes to withstand
\r\nlarge strain when electrodes are charged has attracted the attention of
\r\nmany researcher to study this material for actuator technology. Thus,
\r\nin the past few years Danfoss Ventures A\/S has established their own
\r\ndielectric electro-active polymer (DEAP), which was called
\r\nPolyPower.
\r\nThe main objective of this work was to investigate the dynamic
\r\ncharacteristics for vibration control of a PolyPower actuator folded in
\r\n‘pull’ configuration. A range of experiments was carried out on the
\r\nfolded actuator including passive (without electrical load) and active
\r\n(with electrical load) testing. For both categories static and dynamic
\r\ntesting have been done to determine the behavior of folded DEAP
\r\nactuator.
\r\nVoltage-Strain experiments show that the DEAP folded actuator is
\r\na non-linear system. It is also shown that the voltage supplied has no
\r\neffect on the natural frequency. Finally, varying AC voltage with
\r\ndifferent amplitude and frequency shows the parameters that
\r\ninfluence the performance of DEAP folded actuator. As a result, the
\r\nactuator performance dominated by the frequency dependence of the
\r\nelastic response and was less influenced by dielectric properties.<\/p>\r\n","references":"[1] R. Pelrine, R. Kornbluh, J. Joseph, R. Heydt, Q. Pei, and S.
