介电弹性体致动器（DEA）显示出机器人和机电一体化应用的前景。它们重量轻，成本低，并在实验室演示中表现出良好的性能。然而，这些致动器在经过10多年的发展后，尚未在商业上广泛应用。原因之一是，管理其性能的机制尚未完全理解。因此，设计实用的执行器是困难的。本文的目的是了解VHB 4905/49 10的DEA的主要性能机制。要做到这一点，致动器性能的实验表征进行力，功率，电流消耗，工作输出和效率方面。粘弹性和电流泄漏的关键性能机制确定从实验观察和分析模型的开发。该模型很好地解释了实验观察，并应帮助设计人员选择适用于DEA的应用程序，以及设计有效的DEA。(C)2007 Elsevier B.V保留所有权利。
Dielectric Elastomer Actuators (DEAs) show promise for robotics and mechatronics applications. They are lightweight, low costs, and have shown good performance in laboratory demonstration. However, these actuators have not been widely applied commercially after more than 10 years of development. One reason is that the mechanisms governing their performance are not completely understood. Hence designing practical actuators is difficult. This paper has the objective of understanding the dominant performance mechanisms of DEAs made with VHB 4905/49 10 from 3 M. To do so, an experimental characterization of actuator performance is conducted in terms of force, power, current consumption, work output, and efficiency. Key performance mechanisms of viscoelasticity and current leakage are identified from experimental observations and analytical models are developed. The models explain well the experimental observations and should aid designers in selecting applications that are appropriate for DEAs as well as designing effective DEAs.
