| 摘 要： | 该文介绍了一种使用虚拟仪器(virtual instrument,简称VI)技术进行机械结构模态分析的新方法.利用虚拟仪器开发软件LabVIEW与模态分析软件Star System来完成传统上复杂的机械测试过程.该方法是:通过虚拟仪器开发软件LabVIEW(G语言)编程控制数据采集卡采集数据,生成具有一定数据格式的文件,然后用Star System专业软件对此文件进行分析,最后完成机械结构模态分析过程.该方法使模态分析实验过程得到了简化,降低了设备成本.用此方法对不同的机械结构进行模态分析,与传统测试方法进行比较,结果证明该方法行之有效.

| Abstract: | A new approach is proposed in this paper in using VI (virtual instrument) for modal analysis of mechanical structure. It combines the developed VI software “LabVIEW” with the software “Star” for modal analysis,and makes program for controlling the data acquisition card, to generate a file with a fixed data format, and applies this file in Star System to complete the experiment of modal analysis. The experimental results for different structures have certified the availability of the approach. |
