摘要：由于有阀压电泵内部阀体所受应力过大易导致阀体失效，本文提出了型开槽式截止阀来减小有阀压电泵内部闵体所受应力。基于铰型开槽式截止阀设计了有阀压电泵，分析了铰型开槽式阀压电泵的工作原理。对铵型开槽膜片进行了受力分析，研究了该压电泵的输出性能及耦合作用下的膜片应力。加工制作了铵型开槽式阀压电泵样机，建立了铍型开槽式阀压电泵的有限元模型，数值计算了流固耦合作用下的阀体应力值。计算结果表明：在压电泵正常输出的驱动频率范围内，当驱动频率为418Hz时膜片所受应力的计算值也达到最大，为81.74MPa。最后，进行了压电泵性能试验。试验结果显示：该压电泵的输出流量最大值和振子振幅最大值均出现在低频段；当驱动电压为160V，驱动频率为5 Hz时，输出流量达到最大，为6.6g/min;驱动频率为4Hz时，压电振子振幅达到最大，为165.8um。文中的研究验证了铰型开槽式阀体压电泵的有效性，并得出当铰型开槽式阀压电泵工作在低频段时，阀门所受应力远小于高频段时阀门的应力值。

Abstract: The valve inside a piezoelectric pump was easy to be failure when it was suffered too much stress concentration. A cymbal-shape slotted check valve was proposed to reduce the stress concentration of the piezoelectric pump . A valve-based piezoelectric pump was designed by using the cymbal-shape slotted check valve , and the working principle of the cymbal-shape slotted check valve based piezoelectric pump was introduced. The stress of the cymbal-shape slotted diaphragm was analyzed, the output performance of the piezoelectric pump was discussed and the stress of diaphragm on fluid-solid coupled interaction was calculated . Then , a prototype for the pump was fabricated . The finite element model of the cymbal-shape slotted check valve based piezoelectric pump was established and the stress of the cymbal-shaped slotted diaphragm on fluid-solid coupled interaction were calculated numerically . The calculation results indicate that the calculated value of the diaphragm is
