| Abstract: | Modeling a dielectric electroactive polymer(EAP) actuator is crucial for the design and optimization of actuators.By combining the large deformation elastic theory of membranes and Maxwell stress,this paper builds a model that describes the electromechanical coupling of dielectric EAP materials.A negative stiffness preload mechanism is analyzed which can significantly improve the actuation characteristics of an EAP actuator,and a model of a conically-shaped dielectric EAP actuator with negative stiffness pr... |
