摘　　要：研究了一种基于双压电晶片的喷嘴挡板式伺服阀,给出了双压电晶片的喷嘴挡板式伺服阀的基本机构。对双压电晶片在不同频率、介质、基板尺寸及晶片厚度下的变形情况进行了深入的分析,并通过试验初步验证了双压电晶片喷嘴挡板式伺服阀的相关性能,给出了流量、压力特性曲线,对试验结果进行了分析,得出了相关的结论。Description of a nozzle-flapped valve based on piezoelectic bimorph, including its basic structure,is given in this paper. Deformations of piezoelectric bimorphs are analyzed under various frequencies, in various media, with different size base plates and thickness of piezoelectric bimorph. Performance of the nozzle-flapper based on piezoelectric bimorph is verified through experiments. The flow characteristic curve and the pressure characteristic curve are provided. Relevant conclusions are gained through the analysis of results from the experiments.
