Abstract

This paper describes the theoretical analysis for changing the stiffness in dielectric elastomer stack actuators (DESA) by electric voltage and investigates the influence of the mounting of DESA. The theoretical calculations are validated by the experimental measurements. The tuning of the stiffness by electrical voltage can be used for small adaptive absorbers to attenuate varying resonance frequencies of a system for example caused by the temperature variations. The best experimental results were reached for the structure with unbonded DESA between stiff plates. The resonance frequency was shifted from 129 Hz to 108 Hz. Besides, the selective mounting of DESA is a promising approach for the adaptive absorber applications.
