Modeling of dynamic characteristics of ionic polymer-metal composite beam near resonant frequencies

摘要

In this paper, the dynamic characteristic of an ionic polymer-metal composite (IPMC) cantilevered beam near resonant frequencies is investigated. A dynamic model is formulated on the basis of beam vibration, charge distribution and charge interactions. Experimental tests are conducted with an IPMC cantilevered beam actuated in frequency domain. Comparison with experimental results shows that the theoretical model is able to predict the dynamic responses of IPMC near resonant frequencies.
