摘要
In this study, we develop an analytical model for an electrohydraulic actuator operating with polyethylene pouches, polydimethylsiloxane backbone plates, and dielectric fluids, to analyze its performance considering the displacement. We assume a soft gripper based on two facing electrohydraulic actuators and theoretically estimate the gripper performance in two respects: the workspace and the grasping force. Finally, we conduct parametric studies by varying three parameters: the length of backbone plate, the amount of dielectric fluid, and the permittivity of the dielectric fluid, to demonstrate the changes in performance according to their values.
