阐述了利用国产超磁致伸缩材料 (GMM )研制的新型气动伺服阀和蠕动机械的结构及工作原理 ,并对它们进行了实验研究 ,实验结果表明 :GMM气动伺服阀具有较宽的压力控制特性、良好的线性度和较快的响应速度 ;GMM蠕动机械结构简单 ,能可靠地实现双向可控运动
The structure and working principle of the new pneumatic servo valve and peristaltic machine developed by using the domestic giant magnetostrictive material (GMM) are expounded and the experimental research is carried out. The experimental results show that the GMM pneumatic servo valve has a wide range of pressure control characteristics , Good linearity and fast response speed; GMM peristaltic mechanical structure is simple and can be reliably achieved two-way controllable movement
