摘要随着科技的日新月异，汽车业，造船业等等诸多行业也随着飞速发展，人们对于产品在使用时的性能要求越来越高。为了使企业产品的制造成本更低、研发周期更短和安全性能更高，一种全新的摇摆试验台问世了。而本文所设计的船舶辅机实验台的液压系统，就是其中一种模拟海上运动的摇摆台的液压系统。该摇摆台能够进行升降、横摇和纵摇三种运动，用于模拟船舶在海上航行时的假想情况，进而在实验室中就能得到受试机械在海上的性能验证。

本文首先对试验台的机械结构进行分析，在简单了解了结构之后，进行力学分析，整合数据之后就能得到液压缸的技术指标，从而可以设计液压元件。根据电液比例闭环控制原理完成了系统的液压原理图的设计，绘制了液压原理图，逐步对液压原理图进行分析，从而透彻的了解液压原理图的工作状态。着重进行了对关键液压元件的选型和校核。介绍了蓄能器选型的基本参数，对中间立柱蓄能器组和作动器上的蓄能器进行计算和选型。确定了泵站的选型，绘制了泵站示意图。51250

ABSTRACT With the progress of science and technology, auto industry, shipbuilding industry and so on many professions also along with the rapid development of people for the product in the use of performance requirements more and more high. In order to make the enterprise products of lower manufacturing costs, shorter development cycle, and safety performance is higher, a new kind of swing test rig. And in this paper, the design of ship's auxiliary engine test bench of hydraulic system, which is a simulation of the maritime movement of the swing machine hydraulic system. The swing machine capable of lifting, rolling and pitching three sports, used to simulate the imaginary situation when ship sailing on the sea, and in the lab, can get a machine on the sea of performance verification.

   This article first analyze the mechanical structure of the test rig, after simple understanding of the structure, is analyzed with mechanics, and integrate data can get hydraulic cylinder of the technical indicators, in order to design the hydraulic components. Finished according to the principle of the electro-hydraulic proportional closed loop control system of hydraulic principle diagram design, draw the hydraulic principle diagram, step by step analysis of hydraulic principle figure, and thorough understanding of the working state of hydraulic principle diagram. Focus on the selection for key hydraulic components and checking. Introduces the basic parameter of the accumulator type selection, to intermediate post on the accumulator group and the actuator calculation and selection of accumulator. Determines the selection of pump station, draw the sketch the pump station. 

Key words: Swing machine； hydraulic system；hydraulic components
