| Research Abstract |
Analyses and experiments on electrostatic field, ionic diffusion and structural coupled deformation are described for ion conductive polymer film (ICPF) and metal composite material. The purpose of this study are : (1) To develop and compare the coupling analysis algorithms suitable for the ICPF actuator deformation analysis ; (2) To determine the constitutive modeling of the ICPF actuator : (3) To consider the necessity of future multiply coupled finite element analysis.
The results obtained in this study are as follows.
1. Coupled analysis algorithms
Deformation tests of ICPF actuator were performed to determine the coupling effect between the deformation and ionic diffusion. Some coupling analysis algorithms are proposed and compared in the view point of accuracy, computation time. Numerical instability of the coupled algorithms were theoretically examined for several types of staggered algorithms. The results were compared with the experimental results.
2. constitutive modeling of the composite material
Finite element coupled analysis were performed for various conditions with non-uniform plating and non-uniform shape to verify the constitutive model. Shell element modeling for the composite material was also examined.
3. necessity of multiply coupled finite element analysis
The limit and the future problem of the coupled modeling was also examined. Multiply coupled finite element analysis including the coupling effect with fluid dynamics is also needed to accurately predict the dynamic deformation of the actuator.
