Abstract
We have carried out the prediction of dynamic behavior of ion conducting polymer actuator by bondgraph method. The energy flow in the ion conducting polymer actuator was divided into the electrical model and mechanical model by bondgraph and we have carried out the simulation of current and displacement of actuator. Moreover, we have performed the experimental measurement of them under the condition of four cations, such as Li^+, K^+, Na^+, Cs^+. The bondgraph simulation results were in good agreement with the experimental results qualitatively and quantitatively. Furthermore, the qualitative electrical and mechanical characteristics of each ion are clarified by the derived each coefficients of bondgraph.
