摘　　要：为了验证QLV-MA2型一体化虚拟式模态分析仪在机械结构实验模态分析中的可靠性和适用性,根据模态分析的基本原理,采用QLV-MA2型一体化虚拟式模态分析仪对典型的机械结构(如简支梁与摩托车车架)进行了模态试验与分析。实验结果表明,模态分析方法通过QLV-MA2型一体化模态分析仪在机械结构中的应用是有效可行的。For the purpose of confirming the reliability and validity in the modal test to these mechanical structures with the integrative QLV-MA2 virtual instrument of modal analysis. According to the basle principle of model analysis, the modal test and analysis on these typical mechanical structures, such as simple supported beam and motorcycle frame, was carried out with the integrative QLV-MA2 virtual instrument of modal analysis. Test results demonstrate that, with the integrative QLV-MA2 virtual instrument of modal analysis, the method in the application of mechanical structures is feasible and effective.
