| Abstract: | By using the fundamental theory of modal analysis,the method of modal measurement is derived and a way to measure the modal parameters of a pitched-blade turbine is given.Comparison of the results from modal analysis and finite element analysis shows that the natural frequencies are almost identical,indicating that modal measurement is a viable method for analysis of the natural frequency of a pitched-blade turbine. |
