Energy-based nonlinear dynamical modeling of dielectric elastomer transducer systems suspended by elastic structures

Abstract This paper presents the Hamilton principle approach to model, design and control mechatronic systems using dielectric elastomer transducers (DET) suspended with elastic structures. An overall dynamical modeling for elastomer-based actuators is presented, taking into account effects, e.g., electrical input quantities, inertia, viscous nonlinear behavior of DETs Energy-based techniques are used obtain a coherent mechanical domains. Based on variational Rayleigh–Ritz method approximate field variable, state space model derived considering various geometric deformations boundary conditions. The presented leads set ordinary differential equations that can be engineering applications. proposed finally applied multilayer DET coupled buckled beam structure analyzed based analytical considerations numerical simulations.
