摘要
提出了一种应用于压电叠堆泵的微位移放大机构,该机构以压电叠堆(积层式压电微位移器)为驱动元件,通过基于三角形放大原理的柔性铰链放大机构,放大压电叠堆的输出位移。同时,设计、研制了实验装置,并在试制样机上对其静、动态特性进行了实验。实验测试结果表明,该机构具有线性良好、高分辨率和高频响应等特点。
In this paper, a micro - displacement magnifying mechanism,which was applied to piezo -stack pump, was presented. The amplifier was driven by piezoelectric multilayer actuators. The displacement of piezoelectric multilayer actuator was amplified by the flexure hinges amplifier based on the principles of triangle amplification. The static and dynamic characteristics were tested on the prototype. The characteristics of good linearity, high resolution and high frequency were approved.
