数字液压技术是一项新技术,它为传统的比例或伺服阀控制系统提供了一种替代方案。数字液压应用,如数字泵、数字阀和执行器、开关惯性液压转换器(SIHC)和数字液压动力管理系统,有望实现高能效和低污染敏感性。数字液压技术的研究是由对高能效液压机的需求推动的,但与其他节能技术相比相对不成熟。本文介绍了SIHC的发展,特别关注过去15年来所开展的工作,并评估了当前SIHC研究中发现的设备配置、性能和控制策略。介绍了高速开关阀的各种设计,并对它们的优点和局限性进行了比较和讨论。最后讨论了目前SIHC的局限性,并对SIHC的未来发展提出了建议。
Digital hydraulics is a new technology providing an alternative to conventional proportional or servovalve-controlled systems in the area of fluid power. Digital hydraulic applications, such as digital pumps, digital valves and actuators, switched inertance hydraulic converters (SIHCs), and digital hydraulic power management systems, promise high-energy efficiency and less contamination sensitivity. Research on digital hydraulics is driven by the need for highly energy efficient hydraulic machines but is relatively immature compared to other energy-saving technologies. This review introduces the development of SIHCs particularly focusing on the work being undertaken in the last 15 years and evaluates the device configurations, performance, and control strategies that are found in the current SIHC research. Various designs for high-speed switching valves are presented, and their advantages and limitations are compared and discussed. The current limitations of SIHCs are discussed and suggestions for the future development of SIHCs are made.
