摘　　要：提出一种利用压电陶瓷片直接驱动的伺服阀,分析了双压电晶片的静、动态特性,制造了双晶片直接驱动式伺服阀样机。该伺服阀具有高于传统电磁式伺服阀的频宽与分辨率,它的机械结构简单,抗干扰能力强。A kind of servo valve directly driven by piezoelectric ceramic was proposed. The proposed servo valve is of broader frequency band and higher resolution ratio than the traditional electromagnetic type servo valve, and has the advantages of a simple mechanical structure and strong anti-interference. The static and dynamic characteristic was analyzed. The prototype servo valve directly driven by double piezoelectric wafer was prepared.
