菱形介电弹性体驱动器预载荷分析

Analysis on the Preload of Diamond Dielectric Elastomer Actuator

  • 摘要: 在分析了介电弹性体驱动器工作原理的基础上,对菱形驱动器力—位移曲线进行测试,并将其与弹性预载荷元件所产生的总等效预载荷进行比较,确定了能使驱动器获得较大输出位移的弹性预载荷元件.实验表明,通电后菱形驱动器能产生21mm的线性位移,介电弹性体面积变化率达到98%,失电后驱动器能恢复到初始状态.

     

    Abstract: The working principle of dielectric elastomer actuator(DEA)is analyzed,and the force-displacement curves of diamond DEA are measured and compared with the total equivalent preload produced by elastic preload parts to determine the elastic preload parts which can make the actuator obtain larger output displacement.Experimental results show that,the diamond actuator can produce a displacement of 21 mm and the area variation ratio of the dielectric elastomer can reach 98% when voltage is applied,and the actuator can retract to its original position when voltage is released.
