数控机床振动测试系统设计和实现 机械制造自动化专业VIP免费

中文摘要摘要：机械永远是制造业的主角，而在加工金属零件时数控机床更加是核心。在数控机床发展的历史道路上，而在所有机械故障中，振动被认为是世界上公认的最大的危害之一。本设计就机床振动采取电测法来进行对机床振动的测量。主要采用的硬件部分有YD68D压电式加速度传感器、QSY7701B小型电荷放大器、1715DC0-30直流稳压电源、A62D接线端子排、PCI8602数据采集卡组成；软件部分则用的VB编写程序，从而测量出机床振动的频率,本设计与网络上部分电测法测量机床振动有所不同，因为机床振动的频率可以用加速度来标识出来，因此我将选择使用加速度传感器，由于加速度是一个很抽象的量，故根据压电效应进一步选择压电式加速度传感器作为本设计的主要硬件部分；而软件部分则采用较为常规的的VB编程软件。程序主要分为3断程序：VB主窗口程序、PCI8602数据采集卡驱动程序和WIN32API接口程序。关键词：电测法、压电式加速度传感器、数据采集卡、VB程序外文摘要TitleThedesignofCNCmachinetoolvibrationtestingsystemAbstractMechanicalmanufacturingindustryisalwaystheprotagonist,andintheprocessingofmetalpartsofCNCmachinetoolsisthecoreofmore.OnthehistoricalpathofthedevelopmentofCNCmachinetools,andinallofthemechanicalfaults,vibrationisconsideredtobeoneoftheworldrecognizedthegreatestharm.Thedesignofmachinetoolvibrationtakeelectrometricmethodtomeasurethevibrationofthemachinetool.ThehardwarepartmainlyusestheYD68Dpiezoelectricaccelerationsensor,chargeamplifier,QSY7701Bsmall1715DC0-30DCpowersupply,A62Dterminalblock,PCI8602dataacquisitioncard;softwarewithVBprogramming,tomeasurethefrequencyofvibrationofthemachinetool,thedesignandthenetworkpartofelectricalmethodformeasuringthevibrationofthemachinetoolisdifferentbecause,themachinetoolvibrationfrequencycanbeusedtoidentifytheacceleration,soIwillchoosetousetheaccelerationsensor,theaccelerationisaveryabstract,soaccordingtothepiezoelectriceffecttochoosepiezoelectricaccelerationsensorasthemainpartofthehardwaredesign;thesoftwarepartisusingmoreconventionalprogrammingsoftwareVB.Theprogramisdividedinto3procedures:brokendriverandWIN32APIinterfaceprogramVBmainwindowprogram,PCI8602dataacquisitioncard.Keywords：electricalmethod,piezoelectricaccelerationsensor,dataacquisitioncard,VBprogram目录前言....................................................................5第一章绪论.............................................................61.1引言..............................................................61.2研究背景与意义....................................................71.3研究现状与实例....................................................81.4振动测试技术的简介与方法选择......................................81.5本论文结构.......................................................10第二章数控机床振动测试系统硬件配置.....................................112.1传感器选择.......................................................112.2数据采集卡选型...................................................152.3电荷放大器选型...................................................152.4电源模块选型.....................................................172.5接线端子排选型...................................................18第三章数控机床振动测试系统软件配置.....................................223.1常用的机床振动测量软件分类及本课题软件选型.......................223.2VisualBasic概论................................................223.3VisualBasic6.0特点.............................................233.4数据采集卡驱动模块...............................................
