摘　　要：以回转支承寿命测试试验为研究课题,采用振动检测方法,构建以信号调理器、数据采集卡和工控机为系统硬件、LabVIEW8.2为软件平台的虚拟仪器测试系统。介绍其硬件构成、传感器安装布置及采用结构化和模块化的软件编程方法等,主要包括数据采集、数据处理、数据读取、数据存储和数据打印等模块。数据处理部分采用以小波分析为主,时域统计分析和频域傅立叶变换为辅的分析方法,提取回转支承在强噪声等复杂背景下的局部损伤及缺陷类故障信号。Taking the life test of slew ring as a research project,by vibration measurement method,a virtual instrument test system is constructed with system hardware of signal conditioner,data collecting card and industrial controller as well as software platform of LabVIEW8.2.The system hardware structure,sensor arrangement and installation as well as structural and modular software programming method are expatiated,which include modules of data collection,data reading,data saving,data printing and etc.In data processing,an analysis method mainly taking wavelet analysis while aided by statistic analysis in time domain and Fourier transform in frequency domain is adopted to pick up failure signals of local damages and deficiencies.
