Abstract
To develop a well designed practical spring-roll dielectric elastomer actuator system, we have to optimize the design parameters of spring-roll dielectric elastomer and develop a voltage supply that is able to pump < br />enough controlled charges and provide a wide range of controlled voltages to the actuator. In this paper, switched based multistage charge pump driven by a controlled low voltage switching power supply and a voltage driver is proposed as a wide range output voltage supply. Spring-roll dielectric elastomer optimal design parameters according to [1] areh1 p=5, h2 p=2, a=10. It is proven that h2 p has a subtle effect on both actuationl1 and dimensionless axial force p/mL2L3 however it has a great effect on the applied voltage required activating the actuator. Furthermore, when l2 p increases, the applied voltage decreases and the problems of high voltage are avoided. Therefore the optimal design parameters modified to l1 p=5, l2 p=5, a=10 instead of l1 p=5, l2 p=2, a=10. In this paper, based on the equations of state, new approaches for designing a spring-roll dielectric elastomer actuator have been developed. The key issue of the actuation range depends upon weather the actuator has a fixed load or variable multi-loads. The achieved results based on the proposed approaches show that the applied voltage has been reduced and the design of the actuator is getting simpler
