Principle and analysis of piezoelectric fluidic generator for fuze

对一种新型引信用压电式射流发电机的工作原理进行了分析研究。指出压电片的基频固有频率与谐振腔的固有频率相同时发生谐振现象,可以提高发电机的电能输出,并推导了压电片及谐振腔的固有频率公式,为该发电机的设计提供了理论依据。压电式射流发电机具有可连续供电、响应速度快、体积小、电磁兼容性好等优点,其作为引信用环境能源具有宽阔的使用前景和利用价值。

The principle of a new type of piezoelectric fluidic generator was studied in this paper. The power output of generator increased when piezoelectric chip occurred resonance.Then deduce the formulas of natural frequency of piezoelectric chip and resonant cavity were dedured which, this supplied the theory basis for generator design. Piezoelectric fluidic generator has characteristics such as continuously power supply, quick activation, small volume and fine electromagnetic compatibility and so on, which has great application prospect and utility value when used as fuze ambient energy resource.
