Abstract

Comparative study on the analysis and experiment for the vibration of a rotating cantilever structure was made in this paper. Analysis results were obtained by using the modeling method which was developed in the previous work. The cross-section thickness variation due to the sensor attachment was additionally considered. In order to verify the accuracy of the analysis results, exerimental results were obtained. The analysis and experimental results were found to be in a good agreement. It was also shown that the aerodynamic and cross-section thickness variation effects significantly influenced the dynamic characteristics of the rotating structure.
