Abstract

Tubular actuators (push InLastor) fabricated from dielectric electro-active polymers (DEAP) have been developed and optimized with focus on high volume roll to roll automated manufacturing techniques and processes by Danfoss PolyPower®. This paper reports the dynamic mechanical behaviour from varying electrical stimulus of a PolyPower push InLastor. A simplified harmonic motion model of a spring load mass is shown to accurately predict the resonant frequency of push InLastors when working as displacement devices. The steady state frequency response results are presented for varying mechanical loads and drive voltage stimuli. The step function transient results are also present for different loading conditions. Methodology to extract parameters for the classic mass-spring-damper is also presented. Similarly, results are presented for the use of push Inlastors as force elements. The electrical to mechanical efficiency of PolyPower push InLastor is estimated.
