介电弹性体线性驱动器研究

为满足未来机电系统对新型驱动器的需求，研究菱形介电弹性体线性驱动器。在分析驱动器工作原理的基础上，通过驱动器力—位移曲线和预载荷关系的分析，确定弹性预载荷元件。驱动器通电后能迅速响应，线性位移达到21 mm，弹性体面积变化率达到98%；驱动器失电后能迅速退回，最终退回到初始位置。通过试验分析电压和负载对驱动器的影响，试验表明：驱动器输出位移取决于电压；负载在驱动器输出力范围内对输出位移影响不大，但会影响其运动速度。并根据驱动器的特点，指出驱动器的应用范围。

Research on Linear Dielectric Elastomer Actuator

To meet the need of future electromechanical system for novel actuator, a diamond dielectric elastomer linear actuator is studied. Based on the working principle analysis of actuator, preload parts are determined through the analysis of the relation between its force-displacement curves and preload. Actuator can respond quickly after power-on, and linear displacement attains 21 mm while area change percentage of elastomer reaches 98%. After power-off, actuator can retract quickly and return to its initial p...
