摘　　要：针对传统机械量测试中存在的问题,以DSP为核心,利用虚拟仪器开发软件LabVIEW构建了基于VI技术的虚拟仪器测试系统,包括数据采集、显示、时域分析、频域分析和数据存储等功能。利用虚拟仪器软件控制数据采集卡采集数据,用Star System专业软件进行数据和机械结构模态分析,完成机械测试过程。实验结果表明:该方法使模态分析过程得到了简化,可降低设备成本,为机械工程领域的信号测试与分析提供一种实用手段。Developed a virtual instrument which had the function of data acquisition,displaying and saving,time domain analysis,frequency domain analysis and so on.It combined the developed VI software LabVIEW with the software star for modal analysis,and made program for controlling the data acquisition card,to generate a file with a fixed data format,and applied this file in the star system to complete the experiment of modal analysis.Using VI for modal analysis of mechanical structure,the system realized data collection,save,display,analysis and processing.Actual working shows that it has the advantage of low-cost,stability,high rate,efficiency and reliability.
