在过去的二十年里，以昆虫为灵感的微型扑翼飞行器(MAV)因其高度灵活的飞行潜力而引起了人们的极大关注。昆虫用拍打机构的共振频率拍打翅膀。谐振驱动是非常有利的，因为它放大了扑动幅度，降低了惯性功率需求。新兴的软驱动器，如介质弹性体驱动器(DEAS)具有大的驱动应变，由于其固有的弹性，DEAS已被显示为一种很有前途的共振驱动候选材料。本文提出了一种双锥DEA结构，建立了描述其准静态和动态性能的数学模型。我们比较了两种最常见的介电弹性体：有机硅弹性体和聚丙烯酸酯胶带VHB的高频性能。实验分析了DEA作为质量振荡器的机械功率输出。用该弹性驱动器驱动扑翼机构，在18赫兹的频率下，扑翼机构的最大扑翼幅度可达63°。
In the last two decades, insect-inspired flapping wing micro air vehicles (MAVs) have attracted great attention for their potential for highly agile flight. Insects flap their wings at the resonant frequencies of their flapping mechanisms. Resonant actuation is highly advantageous as it amplifies the flapping amplitude and reduces the inertial power demand. Emerging soft actuators, such as dielectric elastomer actuators (DEAs) have large actuation strains and thanks to their inherent elasticity, DEAs have been shown a promising candidate for resonant actuation. In this work a double cone DEA configuration is presented, a mathematic model is developed to characterize its quasi-static and dynamic performance. We compare the high frequency performance of two most common dielectric elastomers: silicone elastomer and polyacrylate tape VHB. The mechanical power output of the DEA is experimentally analyzed as a DEA-mass oscillator. Then a flapping wing mechanism actuated by this elastic actuator is demonstrated, this design is able to provide a peak flapping amplitude of 63° at the frequency of 18 Hz.
