摘要:液體傳動是以液體為工作介質進行能量傳遞和控制的一種傳動系統(tǒng)。液壓系統(tǒng)的設計是整個機器設計的一部分，它的任務是根據機器的用途、特點和要求，利用液壓傳動的基本原理，擬定出合理的液壓系統(tǒng)圖，再經過必要的計算來確定液壓系統(tǒng)的參數，然后按照這些參數來選用液壓元件的規(guī)格和進行系統(tǒng)的結構設計。本次設計的主要目的是把這四年來所學到的知識進行總結，理論與實踐相結合，為以后進入工作崗位奠定良好的基礎。本次的設計是參照《液壓設計手冊》，采用傳統(tǒng)設計方法來設計一臺小型液壓機的液壓系統(tǒng)。各章的主要內容如下： 第一章介紹了本次設計的主要內容和液壓傳動的發(fā)展現狀和發(fā)展趨勢。 第二章主要是對液壓系統(tǒng)進行工況分析，工況分析包括運動分析和負載分析，按照分析結果繪制出液壓缸速度圖和負載圖，液壓缸的參數確定，繪制工況圖。 第三章包括液壓缸尺寸參數的確定，液壓缸結構的選擇和液壓缸總成圖的繪制。 第四章主要是液壓缸供油方式的選擇和液壓回路的選擇以及原理圖的繪制。 第五章主要是液壓泵的規(guī)格和電機的型號的選擇和閥類元件和蓄能器、油管等液壓輔助元件的選擇。 第六章包括液壓系統(tǒng)中路管系統(tǒng)壓力損失的驗算，這主要是沿程壓力損失和局部壓力損失，再較準確的調節(jié)溢流閥。還要進行液壓系統(tǒng)發(fā)熱升溫驗算。 本次設計主要成果是最終設計出了一臺小型液壓機的液壓系統(tǒng)，并且在實訓臺上得到了驗證。 關鍵詞：液壓系統(tǒng)；液壓傳動；液壓缸；液壓機；設計
Abstract:Liquid transmission medium to work as liquids energy transfer and control of a transmission system. Hydraulic system design is part of the whole machine design, its task is based on machine USES, characteristics and demands, using the basic principle of hydraulic transmission, draw up a reasonable hydraulic system graph, and then after the necessary calculation to determine the parameters of hydraulic system, then according to the parameters to choose hydraulic components specifications and system structure design.The design of the main purpose is to take this four years the knowledge you have learned to carry on the summary, combining theory with practice is later into jobs lay the good foundation. This design is referring to the hydraulic design manual ", USES the traditional design method to design a small hydraulic hydraulic system. The section main content has a points: The first chapter is preface part, mainly introduces the design of the main content and hydraulic transmission development present situation and trend of development. The second chapter of hydraulic system is working condition analysis, working load and the analysis included motion analysis, according to the analysis result analysis of drawing out the hydraulic cylinder velocity diagram and load figure, hydraulic cylinder of parameters, draw condition figure. The third chapter is hydraulic cylinder of design, including the hydraulic cylinder size parameter is determined, hydraulic cylinder structure choice and hydraulic cylinder assembly drawing. The fourth chapter is hydraulic system diagram, mainly is formulating the hydraulic cylinder injection mode selection and hydraulic loop choice and principle chart drawing. The fifth chapter is components choice, mainly is the specifications and motor pump type selection and valve class components and accumulators, hydraulic auxiliary components pipe of choice. The sixth chapter is hydraulic system, including the checking hydraulic system pressure loss of central tube system checked, this is mainly frictional pressure loss and partial pressure loss, again accurate adjustment relief valve. But to hydraulic system fever warming checking. This design achievements are the final design a small hydraulic hydraulic system, and verified in training platform.
