1、XX大學論文題目名稱液壓榨油機液壓系統(tǒng)及液壓缸設(shè)計液壓榨油機液壓系統(tǒng)及液壓缸設(shè)計【摘要】液壓技術(shù)是當前機械工業(yè)中普遍采用的傳動技術(shù)。它是通過能量驅(qū)動裝置（如液壓泵）,將原動機（如電動機）的機械能轉(zhuǎn)變?yōu)橐后w的壓力能，然后通過封閉的管道、控制元件等，由執(zhí)行裝置（如液壓缸、液壓馬達）將液體的壓力能，轉(zhuǎn)變?yōu)闄C械能以驅(qū)動負載和實現(xiàn)執(zhí)行機構(gòu)所需的直線或旋轉(zhuǎn)運動。作為最典型的液壓傳動機械，液壓機廣泛應(yīng)用于各種壓力加工，其中以四柱式液壓機最為典型，常用于可塑性材料的壓制工藝，如沖壓、彎曲、翻邊、薄板拉伸等，也可進行校正、壓制及粉末制品的壓制工藝。
2、液壓機液壓系統(tǒng)設(shè)計的任務(wù)是根據(jù)液壓機的用途、特點和要求，分析液壓系統(tǒng)的工況，確定各階段的速度、位移、負載。然后利用液壓傳動的基本原理，擬定合理的液壓系統(tǒng)原理圖，再經(jīng)過必要的計算確定液壓缸、液壓泵的主要參數(shù)，然后根據(jù)這些參數(shù)來確定液壓元件的規(guī)格和進行液壓系統(tǒng)的結(jié)構(gòu)設(shè)計，最后對整個設(shè)計進行相應(yīng)的校核，使所有的設(shè)計均滿足設(shè)計要求。系統(tǒng)原理圖的擬定和液壓缸設(shè)計是本課題研究的重點。【關(guān)鍵詞】液壓技術(shù)；液壓機；液壓系統(tǒng)設(shè)計；液壓缸HydraulicsystemdesignandHydrauliccylindersofhydraulicpres
