【摘要】 介绍了合成喷的基本原理 ,并分析了压电驱动合成喷设计的基本思路和关键点。对喷的两个重要部件：压电驱动器和腔体的尺寸设计作了分析和说明。讨论了合成喷的电输入参数 ,选择 并实验研究了驱动器的相关特性。分析认为：压电驱动合成喷的尺寸设计应使， h， m和腔体体积 V较小，而电输入则应选择为较高电压，频率为驱动器谐振基频的方波输入。更多还原

【Abstract】 Basic principles of synthetic jet are introduced and key points of its design are pointed out.The design of two important parts: piezoelectric actuator and cavity is analyzed, the optimization of input parameters are discussed and experimentally investigated. The results show that: small , h,m and V is good for size choice of synthetic jet, electrical input with its parameters as higher voltage, basic reso－ nance frequency, square wave is the most efficient input for work of synthetic jet.更多还原
