| 摘 要： | 模态测试过程中,不可忽略的附加质量会对测试结构的试验模态频率有一定的影响。本文从试验模态分析的理论基础出发,简要阐述了试验模态分析过程中附加质量对测试结果的影响,并以某一特定样品为试验基础,验证不同附加质量下模态测试结果的差异,分析差异产生的原因,从而验证理论基础的正确性,为试验模态分析技术在汽车领域的应用提供案例。

| Abstract: | Additional quality can influence modal frequency in modal test. This paper is based on basis theoretical of experimental modal analysis, and described additional quality how to influence modal frequency. It analyzed the differences between the results of the test mode based on different additional quality, and provided valid case for the use of experimental modal analysis. |
