摘要

我們以一般化微分級數（GDQ）電腦計算方法來做磁縮功能等級材料致動器之熱振動及暫態反應的計算與研究。利用長條薄層疊板中心位置變形量做為致動器之行程來設計與分析該簡單彎曲式磁縮功能等級材料致動器。長條薄層疊板使用三平行層：一層Terfenol-D板及兩層FGM板。這項研究分析之目的為計算該長條薄層疊板熱振動之中心位置變形量，本研究將可應用到機械新零件的開發方面。

We like to use the GDQ (generalized differential quadrature) method to compute and study the thermal vibrations and transient responses of magnetostrictive FGM (functionally graded material) actuators. We consider the center deflection of thin laminate strip as the stroke length to design and analyze a simple bending type of magnetostrictive FGM actuator. The parallel-plies laminate strip consists of one mounted Terfenol-D layer and two layers of FGMs. The purpose of this paper is to calculate the center deflection of thin laminate strips under thermal vibrations. The important of the study might be contributed to the development of mechanical parts.
