摘要摘要转动惯量作为一个重要的工程参数，如何准确地测量转动惯量在工程上具有重大意义。本文针对ZME-1综合力学实验台“三线摆”法测转动惯量测量实验，设计出一套能够较精确的测量物体转动惯量的实验辅助装置。该装置采用非接触测量方式，可以方便、快捷、准确的获取三线摆盘转动的周期信号。经在实验室检验该转动惯量测量装置，能准确稳定的采集到周期旋转信号。关键词：转动惯量，三线摆，实验辅助装置，非接触式测量IABSTRACTABSTRACTThemomentofinertiaasanimportantengineeringparameters,howtomeasurethemomentofinertiaaccuratelyhasamagnificentsignificanceintheproject.ThisthesisbasedonthetrilinearpendulummethodtomeasurethemomentofinertiaattheZME-1comprehensivemechanicalbench.Designingamoreaccuratesystemtomeasurethemomentofinertia,thesystemcandisplayreal-timeswingcycle,automaticallycalculatesthemomentofinertiadata.Designednon-contactmeasurementcanbeconvenient,fast,accurateestimatesofthree-wirependulumrotationcycle.Themomentofinertiameasureequipmenthasbeentestedinthelaboratorythatcancollecttheperiodicturnsignalaccuratelyandstably.Keywords:MomentofInertia,TrilinearPendulum,MeasurementSystem,AssistiveDevices,Non-contactmeasurementII目录目录第1章引言.........................................................11.1研究意义.......................................................11.2国内外研究现状.................................................11.3主要研究内容...................................................2第2章转动惯量的运用研究与测量......................................42.1转动惯量的物理意义及其运用.....................................42.2现有的转动惯量测算方法..........................................62.3各种测算方法分析...............................................10第3章测试装置设计.................................................123.1测试装置技术要求..............................................123.2总体方案设计..................................................123.2.1电气系统方案...............................................133.2.2机械系统方案...............................................14第4章电气系统原理及设计...........................................164.1传感器信号放大与处理...........................................164.1.1光电池工作原理.............................................164.1.2单片机控制光电池计数原理...................................174.1.3信号采集模块...............................................184.2单片机及其外围电路设计........................................194.2.1单片机电路设计.............................................204.3LED显示模块...................................................214.4电源模块设计..................................................24第5章机械结构设计.................................................275.1设计流程......................................................275.2摆盘夹取装置的设计.............................................285.2.1释放机构设计...............................................295.2.2夹头设计...................................................305.3定位移动装置的设计............................................305.3.1移动装置设计...............................................315.3.2定位装置设计...............................................32III目录5.4转角控制和传感器装夹装置......................................335.4.1转角控制方式...............................................335.4.2激光器和光电池装夹装置......................................
