压电叠堆压电泵直线马达液压缸 piezostack piezoelectric pump linear motor cylinder

摘要

提出一种利用压电叠堆泵驱动的新型直线马达(简称压电液压马达),介绍了其系统构成及工作原理,并进行了理论及试验研究。理论分析结果表明,压电液压马达的性能是由压电振子／泵腔／截止阀／液压缸的结构尺寸、负载及工作频率等多种要素共同决定的,只有当相关要素合理配置时才能实现压电液压马达的预期功能。在其他参数确定的情况下,当负载为其最大驱动力的二分之一时输出功率和能量最大。利用尺寸为4 mm×4 mm×80 mm的压电叠堆制作了腔体直径为30 mm的压电泵,并对其直接输送流体及驱动液压缸时的流量、压力及功率等性能进行了测试与对比分析。结果表明,采用直径为15 mm的液压缸时,压电液压马达的最大速度、推力及功率分别为12.5 mm/s、32 N和93 mW。

Abstract

A novel linear hydraulic motor driven by piezostack pump (piezohydraulic motor) was presented, and its structure and working principle were introduced. With establishing the static-state model, the influence factors of the piezohydraulic motor were picked up and analyzed. The theoretic results show that the output capability of the piezohydraulic motor depends on the structure and size of the piezostack/pump-chamber/check-valve/cylinder, the driving frequency and even the external load. The desired performance of piezohydraulic motor will not be achieved unless the relative parameters are matched well. Moreover,when an applied load is equal to half of the blocking force, the maximal output power can be obtained. A piezostack pump with 30 mm chamber-diameter was fabricated using a piezostack in 4 mm×4 mm×80 mm,and the experiments on the unattached pump and the overall piezohydraulic motor were carried out for comparison on their flowrates, pressures and output powers. Analyzed results show that the maximal thrust, velocity and the power of the piezohydraulic motor are 32 N, 12.5 mm/s and 93 mW, respectively,when a cylinder with chamber diameter of 15 mm are utilized.
