摘要: Ionic polymers have attracted considerable attention due to their interesting sensing and actuating behavior which make them a proper choice for use in wide range of applications including biomimetic robots biomedical devices. The complicated electro-chemo-mechanical dynamics ionic polymer actuators is drawback functional Therefore, establishing mathematical model could effectively predict the actuators' dynamic great interest. In this paper, model, named equivalent thermoviscoelastic (EDT) based on thermal analogy beam theory proposed analysis bending-type actuators. Then, developed extended analyzing performance actuator finite element software. enables consideration material geometric nonlinearities facilitates modeling devices approach validated using experimental data.
