摘要
Dielectric elastomer actuators (DEA) are a new class of actuators, exhibiting electric field-induced strains. Upon electrical stimulation they can provide large strains and consequently electrical forces. These abilities along with their high compliance make them candidates for active vibration control. This parer presents a general framework for the usage of DEA as elements of active vibration control systems. The electrical and mechanical model of the DEA and a basic control law, for varying the voltage, is reviewed. The basic idea is to reduce the acceleration of the vibrating equipment when the system approaches its equilibrium. The application of the actuator in a single-dof-mass-spring system is modeled. The results with and without control are presented and show the large capabilities of the actuator to suppress the vibrations induced by an external force. DEA has viscoelastic properties, which can further increase the damping capabilities of the vibration absorber but on the other hand produce a time delay, which must be taken into account. Furthermore, the technological issues arisen-structure of the actuator, power and equipment needs, effect of prestrain and frequency, distributed actuation- are discussed.
