摘要：随着电气控制技术的发展，绿色环保等理念的诞生，液压技术模块化设计、电液整合与控制、变频调节等技术又有了新的进展，随之而来的是，液压传动与控制技术需要进一步提高。为了适应现代科技发展的变化，液压站也要在原有的设计基础上做出改变和发展，本课题是特定工作环境下，设计具有高性能，绿色环保，高经济性的液压站。在设计过程中出现了许多问题，如：在设计液压系统图上，由于对真实液压系统了解不够透彻，导致液压系统中原件种类数量不够完整，经老师指点和查阅资料后才得以解决；在液压系统理论计算过程中，对油液压力损失和发热升温数值计算不够明确，经老师指点后才得以解决；在图纸绘制过程中，一些紧固件连接方式不明确，最后询问老师，查阅资料后方可继续进行。在将近6个月的时间中，得到液压站装配图一张、零件图四张，液压站设计计算，力学性能、寿命实效等校核，控制系统的设计等。

Design of hydraulic station for electro-hydraulic servo control test system

Abstract: With the development of electrical control technology and the birth of some concepts such as green and environmental protection, the modular design of hydraulic technology, electrohydraulic integration and control, frequency conversion speed regulation and other technologies have made new progress. Accordingly, hydraulic transmission and control technology should be much improved. In order to adapt the changes in the development of modern science and technology, the hydraulic station should also make changes and developments on the basis of the original designs, his topic will design a hydraulic station with high performance, green environment and high economy when it under a specific condition. In the design process, there are many problems. For example, due to not thorough understanding of the real hydraulic system, the types of the original parts in the hydraulic system are not complete. And in the theoretical calculation of hydraulic system, numerical calculation of oil pressure loss and heating temperature can not be clearly defined. Thanks to teacher's instructions, those problems are solved. When in the process of drawing, some fastener connection is indeterminate. At the result we all solved it by teacher's help and material reading. In nearly 6 months, an assembly drawing of hydraulic station, four pieces of part drawing, design and calculation of hydraulic station, verification of mechanical properties and lifetime effects, design of control system and so on were completed.

Keywords: Hydraulic station; electro hydraulic servo; hydraulic system; test-bed; practical hydraulic technology
