项目摘要

An electro-conjugate fluid (ECF) has an interesting effect in which a jet flow is generated between two electrodes, when a high voltage is applied to the electrodes. Piston type actuators were constructed using two different structures for the exciting ECF jets : a coil based structure and a mesh based structure. The fundamental characteristics of the actuators were clarified by the experiments. Then, as a drive method for the actuators, an optical drive method using PLZT ceramics with a photoelectric effect was developed. An optical drive type linear actuator system was constructed in which the linear actuator and the optical drive method were combined. This system has the excellent advantages for non-contact drive and high electromagnetic compatibility. The important results are as follows.1. Both of the proposed linear actuators showed fairly good static characteristics and potential for functional improvement.2. In the coil type actuator, the piston speed and the electric current flow between the electrodes grew approximately in proportion to the applied voltage. The mesh type actuator showed similar characteristics.3. The load -speed characteristics of the actuators were similar to those of general DC motors.4. It was shown that the ECF actuators can be operated by the optical drive using PLZT ceramics.

电共轭流体(ECF)具有一种有趣的效果，即当向两个电极施加高电压时，在两个电极之间产生射流。采用两种不同的结构构造了活塞式执行器，用于激励ECF射流：基于线圈的结构和基于网格的结构。通过实验，阐明了执行器的基本特性。然后，作为驱动器的驱动方式，提出了一种利用具有光电效应的PLZT陶瓷实现光驱动的方法。将直线驱动器与光驱动方法相结合，构建了一种光驱型直线驱动器系统。该系统具有非接触式驱动、电磁兼容性高等优点。主要结果如下：1.本文的主要研究成果如下。两种直线驱动器都表现出了较好的静态特性和功能改进的潜力。在线圈式驱动器中，活塞速度和电极之间的电流与施加的电压大致成正比增长。网格型驱动器也表现出类似的特性。该执行器的负载-速度特性与普通直流电机相似。结果表明，采用PLZT陶瓷的光驱可以驱动ECF驱动器。
