摘要：
在压电陶瓷（PZT）和超磁致伸缩材料（GMM）两种功能材料的特性研究基础上，设计一种耦合PZT/GMM微动力构件。通过分析微动力构件的工作原理，得知其输出力受到电压、气隙、温度等因素的影响。该文就电压和气隙两种影响因素分析微动力构件的输出力，通过对比理论分析和实验结果得到：在10~120 V电压调节范围内，电压升高微动力构件输出力呈非线性增长，且这种增长效应在气隙越小时表现越明显；恒定电压条件下，在0~1.2 mm微动力构件气隙增大，微动力构件输出力呈非线性减小。

Abstract: Based on the study of the characteristics of two kinds of functional materials,piezoelectric ceramic (PZT) and giant magnetostrictive material (GMM),a coupled PZT/GMM micro dynamic component is designed.By analyzing the working principle of micro dynamic component,it can be known that the output force of the micro power component is affected by the factors such as voltage,air gap and temperature.The effect of voltage and air gap on the output force of micro dynamic component is analyzed in the paper.Through comparative theoretical analysis and experimental research,the effects of the voltage and air gap on the output force of the micro dynamic component are got.In the range of 10-120 V voltage,the output power of the micro dynamic component increases nonlinearly with the rise of voltage,and the smaller the air gap,the more obvious of the rise effect.Under constant voltage,however,from 0 to 1.2 mm of the air gap,the output power of the micro power component decreases nonlinearly.
