摘　　要：伺服电机泵是电静液作动器的核心动力和控制部组件,其制约了作动器的极限输出性能。国际知名液压技术研究机构,如穆格、派克等,已推出了用于航空航天和高端民用装备的系列产品。近年来,中国多个科研机构及高等院校对高性能伺服电机泵开展了多方面技术研究,取得了一些突破性的进展,但关键技术仍不成熟。从航空航天应用特点出发,结合机器人、航海以及工业设备等多个领域,对高性能伺服电机泵相关研究进行了综述,总结了其发展和应用情况,分析了其在高端应用场景下的高功密、高动态、长寿命、低噪音和智能化等关键性能需求,基于此讨论了其在机理研究、设计理论和组件强化等方面的技术难点,为高性能电静液作动和核心部组件技术的进步提供支撑。Servo Motor Pumps(SMP)play a decisive role as central power and control elements for the performance limits in Electro-Hydrostatic Actuators(EHAs).Internationally renowned hydraulic companies such as Moog and Parker have introduced SMPs for aerospace and high value Industrial applications.In recent years,Chinese research in the field of high-performance SMPs has made some progress,but is still far from mature.This article provides a comprehensive overview of SMPs in terms of aerospace applications and also considers other fields such as robotics,marine and industrial applications.Based on the analyzed applications and developments,the five key performance characteristics such as high power-to-weight ratio,high dynamic range,long service life,low noise and intelligence are summarized,and the difficulties in theory and key technologies are discussed to make suggestions for high-performance EHAs and their key components.
