Abstract

This paper presents experimental investigations on valve actuator and pumping actuator of a piezo-hydraulic pump with active valves. Quadratic arm flexurally amplified piezoelectric actuators (QAFAPA) are designed for the pumping actuator and the valve actuator. Simulations are carried out to determine the voltage-displacement characteristics of the QAFAPA using MATLAB/Simulink software. To perform the pumping action, slotted pumping diaphragm is designed considering acrylic as the material and is analyzed for its stiffness using ANSYS analysis software. The slotted pumping diaphragm is fabricated, and the stiffness is experimentally determined which matched well with the analysis result. One pumping actuator and one actuator similar for inlet and outlet valve is developed. Voltage-displacement experiments are carried out on the valve actuator and the pumping actuator. Further, the displacement of the slotted pumping diaphragm when assembled with pumping actuator is experimentally determined. Simulation and experimental results were compared, and the results obtained were in good agreement with each other.

压电液压泵阀及泵动器的建模与实验验证

本文对一种主动阀式压电液压泵的阀致动器和泵致动器进行了实验研究。针对泵动器和阀门动器设计了二次臂柔性放大压电作动器(QAFAPA)。利用MATLAB/Simulink软件对QAFAPA的电压位移特性进行了仿真。为了实现泵送动作，设计了以丙烯酸为材料的开槽泵送膜片，并利用ANSYS分析软件对其刚度进行了分析。制作了缝状抽气隔膜，并对其刚度进行了实验测定，结果与分析结果吻合较好。研制了一种用于进出口阀的泵送执行机构和一种类似的执行机构。对阀门执行器和泵送执行器进行了电压位移实验。此外，通过实验确定了与泵送执行器组合在一起时，槽式泵送隔膜的位移。仿真结果与实验结果进行了比较，结果吻合较好。
