Engineering research in fluid power: a review

This article reviews recent developments in fluid power engineering, particularly its market and research in China. The development and new techniques of the pump, valve, and actuator are presented in brief with a discussion of two typical modern fluid power systems, which are the switched inertance hydraulic system and the hydraulic quadruped robot. Challenges and recommendations are given in four aspects including efficiency, compactness and integration, cleanliness, and fluid power education.摘要本综述详细介绍近年来流体传动技术的发展现状, 特别是该学科在中国的研究开展现状以及应用市场。 同时详细讨论液压泵、 阀及执行元件的发展与新技术, 以及液压惯性切换系统和液压四足机器人两个典型的现代流体传动系统。 并从液压系统效率、 集成一体化、 系统清洁和流体传动学科教育四个方面讨论当前研究人员所面临的挑战, 并提出相关建议。
