摘要
本研究基于蛙腿的灵感,利用粘滑原理开发了一种具有灵活机制的新型压电致动器。它采用双足设计,滑块可由一只脚或两只脚交替驱动,这取决于所使用的两个 PZT 叠层的激励情况。PZT 叠层的伸展可以通过蛙腿的启发作用传递到两个驱动脚上的垂直和水平变形。它们用于按压和驱动滑块。本文介绍了这种致动器的构造,并说明了其工作原理。为研究其静态性能,还进行了有限元模拟。制作了拟议致动器的原型,并测量了一系列机械输出特性。结果表明,当电压和频率分别为 100 V 和 400 Hz 时,拟议制动器的输出速度为 4.23 mm/s。在电压为 100 V 时,最大垂直负载能力为 9 N。这项工作中的相应结果验证了基于蛙腿启发提出的具有灵活机制的双足压电致动器的可行性。
Development of a bipedal piezoelectric actuator with flexible mechanism based on the frog-leg inspiration
A new piezoelectric actuator with flexible mechanism using stick-slip principle based on the frog-leg inspiration is developed in this work. It utilizes bipedal design, and the slider can be driven by only one foot or two feet alternately, which depends on the exciting situation of the used two PZT stacks. The extension of the PZT stack can be transmitted into the vertical and horizontal deformations on two driving feet due to the frog-leg inspiration. They are used to press and actuate the slider. The configuration of this actuator is presented and its working principle is illustrated. Finite element simulation is carried out to investigate the statics performance. A prototype of the proposed actuator is fabricated and series of mechanical output characteristics are measured. The results demonstrated that the proposed actuator obtained the output velocity of 4.23 mm/s when the voltage and frequency were 100 V and 400 Hz. The maximum vertical loading capacity was 9 N under the voltage of 100 V. The corresponding results in this work validated the feasibility of the proposed bipedal piezoelectric actuator with flexible mechanism based on the frog-leg inspiration.
