摘　　要：针对传统压电泵输出性能低的问题,通过分析圆环形压电振子的特性,建立了一个压电振子受力模型。并在此基础上运用系统共振原理,成功实现了流体之间的单向流动,由此设计出了一种惯性式压电驱动隔膜泵。并利用有限元仿真计算方法对该设计进行仿真分析。结果显示,惯性式压电驱动隔膜泵的最大输出力为52 N,与普通压电隔膜泵的最大输出力47 N相比,提高了10.63%。综合可以看出,基于有限元仿真计算的惯性式压电驱动隔膜泵的设计与分析,有效提高了输出性能。In response to the problem of low output performance of traditional piezoelectric pumps,a force model of piezoelectric oscillators was established by analyzing the characteristics of circular piezoelectric oscillators.On this basis,the principle of system resonance was applied to successfully achieve unidirectional flow between fluids,resulting in the design of an inertial piezoelectric driven diaphragm pump.And use finite element simulation calculation method to simulate and analyze the design.The results show that the maximum output force of the inertial piezoelectric driven diaphragm pump is 52N,which is 10.63%higher than the maximum output force of the ordinary piezoelectric diaphragm pump of 47N.Overall,it can be seen that the design and analysis of an inertial piezoelectric driven diaphragm pump based on finite element simulation calculation have effectively improved output performance.
