摘  要
 工程機械行業對液壓油缸的需求量越來越大，質量要求越來越嚴，為可減小整機裝配后的調試工作量，有必要對所選用的液壓油缸在整機裝配前進行檢驗。
 液壓缸出廠前的試驗是檢驗液壓缸性能指標的重要試驗之一，其試驗所測數據的準確性直接關系著液壓缸的性能。以往用于生產的液壓缸試驗臺往往精度較差、自動化程度低，大大地影響了生產效率的提高，不能滿足生產的需要。根據需要，并綜合考慮質量、效率和安全實用性，選擇簡易油缸打壓試驗臺方案，力求設計出結構簡單、工作可靠、成本低、效率高、操作簡單、維修方便的系統。                                                 
 本文通過結構設計、理論設計計算、強度校核、工作原理及性能分析，對方案作了詳細說明，主要研究油缸打壓試驗臺的機械打壓方式、結構和穩定性，同時，研究液壓系統的完整優化簡易設計路線元件及參數，完成試驗工藝分析。

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.
