摘要液压支柱在采煤工作面支护方面起到了很重要的作用。液压支柱冲击试验台作为测试液压支柱在抗冲击载荷方面能力的设备，能否快速，准确的检测液压支柱性能对于保障安全生产，提高经济效益具有重要意义。但是目前对于液压支柱冲击试验台的设计研究却很少。本文结合课题需要，对试验台的机械结构进行改造设计，以便为今后的工作打好基础。试验台机械结构采用卧式框架结构，双液压缸同步动作，降低了单个液压缸所需压力，增加了冲击过程试验台的刚性和强度。试验台液压系统动力源采用限压式变量泵，采用分流集流阀的同步回路，采用蓄能器的冲击加载回路，保证冲击过程所需冲击力大，速度快同时保护其他原件的要求。为了提高试验台的测试精度和自动化水平，本文采用了PLC对整个液压系统进行控制。关键词：液压支柱冲击试验台；结构设计；框架结构；PLCAbstractHydraulicpropsupportinthecoalfacehasplayedaveryimportantrole.Hydraulicproptestrigfortestingtheimpactofhydraulicshockloadcapacityinthebackboneoftheequipment,canquicklyandaccuratelytesttheperformanceofhydraulicpillarsofsafetyfortheprotection,improveeconomicefficiencyisofgreatsignificance.However,theimpactofthecurrentteststandforhydraulicpillardesignresearcharefew.Thisissueneedsintegration,andtest-beddesignedtotransformthemechanicalstructureinordertolaythefoundationforfutureworkMechanicalstructuretestbedframestructurewithvertical,double-actionhydrauliccylindersimultaneously,reducingthepressurerequiredforasinglehydrauliccylinder,anincreaseoftest-bedimpactprocessrequiredrigidityandstrength.Testhydraulicsystempowersourceislimitedpressure-typevariablepumpsetswithflowdiversionvalvesynchronizationloop,usingtheimpactloadaccumulatorcircuit,theimpactoftheprocessrequiredtoensurethattheimpactforce,speed,whileprotectingtheotheroriginalrequirementsInordertoimprovetestaccuracyandtest-bedlevelofautomation,weuseaPLCtocontroltheentirehydraulicsystem.Keywords:Impactteststandhydraulicprop；StructuralDesign；Framework；PLC目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc295802592"第1章前言PAGEREF_Toc295802592\h1HYPERLINK\l"_Toc295802593"1.1课题研究的背景和意义PAGEREF_Toc295802593\h1HYPERLINK\l"_Toc295802594"1.2液压实验台的国内外研究现状PAGEREF_Toc295802594\h2HYPERLINK\l"_Toc295802595"1.3课题的主要目的PAGEREF_Toc295802595\h2HYPERLINK\l"_Toc295802596"1.4本文主要设计流程PAGEREF_Toc295802596\h2HYPERLINK\l"_Toc295802597"1.5本次液压支柱冲击试验台系统设计参数PAGEREF_Toc295802597\h2HYPERLINK\l"_Toc2958025
