圆盘水浸超声扫描装置设计VIP免费

北京理工大学珠海学院2020届本科生毕业设计圆盘水浸超声扫描装置设计圆盘水浸超声扫描装置设计摘要水浸超声检测用水作为耦合剂，探头不直接接触工件，可以减少对工件表面粗糙度的要求，减少探头的磨损。自动化检测更是如今无损检测发展的大趋势。随着圆盘工件在航空航天领域的广泛应用，研究圆盘类零件的水浸超声自动检测系统具有重大意义。本设计基于圆盘工件在超声自动化检测中的研究现状，设计了一款圆盘水浸超声扫描装置设计，装置主要由水箱、三轴扫查架以及转动装置组成。本设计通过计算机上的LabVIEW程序向运动控制卡发出指令，运动控制卡收到指令后发送信号驱动步进电机带动探头的移动以及工件的转动。关键词：圆盘；超声检测；水浸法；步进电机；自动化检测北京理工大学珠海学院2020届本科生毕业设计北京理工大学珠海学院2020届本科生毕业设计Designofthewater-immersedultrasonicscanningdeviceofthediscAbstractThecouplingagentusedinultrasonictestingforwaterimmersioniswater.Theprobedetectstheworkpiecethroughthewaterlayerwithoutdirectcontactwiththeworkpiece.Ontheonehand,itcanreducethesurfacefinishrequirementsoftheworkpiece,andontheotherhand,itcanalsoreducethewearontheprobe.AutomatedtestingisnowthedevelopmenttrendofNDT.Itisveryimportanttostudytheimmersionultrasonicautodetectionsystemofdiskpartsinawiderangeofdiskprocessinginaerospace.Thisdesignisbasedontheresearchstatusofdiscworkpieceinultrasonicautomaticdetection,designedadiscwaterimmersionultrasonicscanningdevicedesign,thedeviceismainlycomposedofwatertank,threeaxisscanningframeandrotatingdevice.ThisdesignsendsinstructionstothemotioncontrolcardthroughtheLabVIEWprogramonthecomputer.Afterreceivingtheinstructions,themotioncontrolcardsendssignalstodrivethesteppermotortodrivethemovementoftheprobeandtherotationoftheworkpiece.Keywords:disc；Ultrasonictesting;Waterimmersion;Steppermotor;Automatedtesting北京理工大学珠海学院2020届本科生毕业设计北京理工大学珠海学院2020届本科生毕业设计目录1前言...............................................................................11.1本设计的目的、意义及应达到的技术要求.........................................11.2本设计在国内外的发展概况.....................................................11.3本设计应解决的主要问题.......................................................22本设计.............................................................................22.1相关理论.....................................................................32.1.1检测方法...............................................................32.1.2电机...................................................................42.1.3探头...................................................................52.1.4运动控制卡.............................................................62.1.5LabVIEW软件...........................................................62.2设计过程.....................................................................72.2.1水箱的设计.............................................................72.2.2三轴扫查架的设计.......................................................82.2.3试件参数...............................................................82.2.4探头的选择及探头的夹持装置.............................................92.2.5电机及驱动器的选择....................................................102.2.6运动控制卡的选用......................................................112.2.7转盘的设计............................................................122.2.7.1所需材料.....................
