【摘要】 由于现有的压电泵采用的压电振子结构限制了压电泵性能,为了提高压电振子的变形量和压电泵频响,从而提高流量的角度出发,提出采用Cymbal结构作为压电振子,设计并制作而成了一种双腔体结构同步驱动的无阀微型压电泵,用Ansys8.0有限元软件对压电振子进行了分析,得出了结构参数对压电振子性能的影响,为后续的此类压电泵优化设计奠定了基础。更多还原

【Abstract】 Due to the piezoelectric bimorph of generic piezoelectric pump, the preferment of the pump has been restrained. However, a new structure that is called Cymbal was adopted as the piezoelectric bimorph. By the theoretic analysis, numeric calculation and simulation, the dependence of the piezoelectric properties of Cymbal actuator on the dimensions of metal end cap and piezoelectric ceramic was studied and a new piezoelectric pump was schemed out.更多还原
