| Abstract: | 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, |
