摘要
设计了一种以Cymbal振子为驱动器的新型无阀微压电泵。研究了Cymbal振子的工作过程。在Cymbal振子有限单元模型的基础上,对其工作过程进行仿真分析。通过模态分析得到了Cymbal振子的前5阶固有频率和振型,选出其中最符合工作要求的频率和振型;通过瞬态分析,结合压电耦合分析,得到了振子在方波电压作用下的瞬态动力学特性。
A new type of valveless piezoelectric pump driven by Cymbal actuator was put forward, The working process of Cymbal actuator was simulated by FEM （finite element methods）. Based on establishing the FEM model of Cymbal actuator, modal analysis was carried out to calculate modal frequency. The just working frequency was obtained by calculation. By transient dynamics analysis applying piezoelectric coupling theory, the transient dynamics properties have been discussed. The analysis result provided a design reference on this kind of valveless piezoelectric pumps that use Cymbal actuators.
