摘要

本文針對應用壓電材料原理之致動器之振動模態作一深入研究。致動器方面，是利用8片壓電片串接而成的曲線機構，依照驅動電流的不同，分別為直流電與諧波之交流電，可有定位及傳送兩種功能。本文建立了曲線機構之靜、動態的理論分析，並加以模擬分析，在定位平台部分，是改變輸入電壓的大小，以控制輸出端的位移量，經實驗發現，其解析度約為 ，再設計添加一補強機構，解析度更可提升至 ，精密度算是相當不錯；而在輸送平台部分，原理為運用行進波帶動被輸出物，本文建立被輸送物之運動模式，設計所需的頻率與振幅，以其能達到最佳之輸送效率，最後配合實驗驗證實體機構，實際製作提升工作頻率的機構，大幅改善其輸送速度、安全性與精密度。

This paper in an advance research about the actuator driven by piezoelectric principle.For the actuator,is the meander-line connected by eight piezoelectruc ceramics,it has two capabilities separately are to poisiton and transport driven by DC and AC power.This paper built series of theoretical model of meander-line in both static and dynamic states and also built the simulation and analysis about meander-line,for the poisiton building ,we can control the displacement of the output connector by change the voltage,to find the resolution about in experiment,and the resolution is about when applied a stiffener on the meander-line,it might be considered as a fine resolution about this mechanism.For the transport building,the principle is to transport the parts by traveling wave,the motion of parts has also been built theoretical to design the necessary vibration frequency.Finally,we test the real meander-line mechanism .We can get a better transferring rate,safety,and precision when the meander-line has higher operating frequency.
