摘要
本文主要介绍了理论和试验模态分析的建模方式、分析方法以及应用过程。讨论了分析方法的适用条件及为提高模态分析精度需要解决的问题。并以悬臂梁为例,使用DASP软件验证了模型的一致性及方法的可靠性;该理论分析及应用过程对促进模态分析法的工程应用具有重要意义。
The aim of the paper is to study two methods of modal analysis, theoretical and experimental modal analysis, including the mode of modeling,the measure of analysis and the process of their implementation. The applicable condition and problems that need to solve are discussed as well. Furthermore, the reliability of two models and the feasibility of two methods are validated by modeling on cantilever beam and using the DASP software, The theoretical analysis and the application of software are more important for the use of modal analysis in engineering,
