摘  要
 工程机械行业对液压油缸的需求量越来越大，质量要求越来越严，为可减小整机装配后的调试工作量，有必要对所选用的液压油缸在整机装配前进行检验。
 液压缸出厂前的试验是检验液压缸性能指标的重要试验之一，其试验所测数据的准确性直接关系着液压缸的性能。以往用于生产的液压缸试验台往往精度较差、自动化程度低，大大地影响了生产效率的提高，不能满足生产的需要。根据需要，并综合考虑质量、效率和安全实用性，选择简易油缸打压试验台方案，力求设计出结构简单、工作可靠、成本低、效率高、操作简单、维修方便的系统。                                                 
 本文通过结构设计、理论设计计算、强度校核、工作原理及性能分析，对方案作了详细说明，主要研究油缸打压试验台的机械打压方式、结构和稳定性，同时，研究液压系统的完整优化简易设计路线元件及参数，完成试验工艺分析。

Abstract
 The hydraulic ram's demand of engineering machinery profession is getting much wider, and the quality requirement is getting more and more stricter. In order to reduce the debugging work load after may complete machine assembly, it is necessary to take the examination on the hydraulic ram which selects before the complete machine assembly.
 The experiment examines before hydraulic cylinder leaving the plant is one of the important experimental for hydraulic cylinder performance index. The accurate to its laboratory measures data is have a direct impact on the Performance of the hydraulic cylinder. Formerly the hydraulic cylinder test platform which used in produces being often bad for precision , the automaticity just to be low. It has affected the production efficiency enhancement greatly and cannot satisfy the need of its production. According to this, as well as the overall consideration to the quality, the efficiency and the security usability, we choice the plan named the simple cylinder suppression test platform, which makes every effort to design a system for simple structure, reliable operation, low cost, high efficiency, simplicity of operator, and service convenient.
 The article has given detailed to showing the plan through its structural design, the theoretical computation design, the intensity examination, the principle of operation and the performance analysis. It mainly studies the way of the machinery suppression for cylinder test platform, the structure and the stability. on the other hand , doing the research for perfect optimized simple design route part and the parameter of hydraulic system, and complete the study of the experiment process.
