毕业设计（论文） PAGE 2 摘 要 液压传动系统的整个设计流程主要分为两大部分：一是系统的功能原理设计；二是系统的结构设计也称施工设计，它包括液压装置及电气控制装置的设计。液压系统的功能原理设计完成之后，即可根据所选择的液压元件和辅助动作顺序图表，进行液压系统的结构设计。??? 液压装置设计(泛指液压系统中需自行设计的那些零件的结构设计的统称)的目的在于选择确定元、辅件的连接装配方案，具体结构，设计和绘制液压系统产品工作图样，并编制技术文件，为制造、组装和调试液压系统提供依据。电气控制装置是实现液压装置工作控制的重要组成部分，是液压系统设计中不可缺少的重要环节。电气控制装置设计是根据液压系统的工作节拍或电磁铁动作顺序表，选择确定控制硬件并编制相应的软件。??? 液压装置设计是液压系统功能原理设计的延续和结构实现，一个液压系统能否可靠而有效地运行，在很大程度上取决于液压装置设计的质量优劣，从而使液压装置结构设计在整个液压系统设计过程中成为一个相当重要的环节，所以在设计的时候必须给予足够的重视。 关键词：液压传动、试验台 ABSTRACT The whole design of hydraulic transmission system mainly divided into two major process: One is the function of the system design principle, Second is the structure design and system construction design, it includes says hydraulic device and electric control device design. Hydraulic system design, function and principle can be chosen according to the order of hydraulic components and auxiliary motion, hydraulic system graph structure design. Hydraulic device in the hydraulic system design (referring to those parts of the design of structure design of the purpose of) referred to choose one yuan, the connection assembly scheme, design, structure and drawing hydraulic system products and technologies, the working pattern for manufacturing, assembling, files and debugging hydraulic system provides the basis. The electrical control device is to realize the control of hydraulic equipment work is an important part of hydraulic system design indispensable important segment. The electrical control device is designed according to the hydraulic system of working rhythm or electromagnet work order list, select the corresponding control hardware and determination of the software. Hydraulic device is designed to function and principle of hydraulic system design and realization structure, a hydraulic system is reliable and effective operation, depends in large part on hydraulic device design quality, thus making hydraulic structure design in the hydraulic system design process becomes a very important l
