Modal characteristic optimization of the blade of the test rig

Medůna O., Vomáčko V., Pustka M., Prošek A.
pages 163 - 166, full text

Article is focused on modal characteristic of the blade which is important component of the experimental test rig for blade flutter measurement. Modal characteristics are obtained using experimental (EMA) and simulation (SMA) modal analyses. The MAC criterion is used for comparison of eigenmodes of the individual material variants. The main aim is to increase the first eigenfrequency (corresponding to the torsional eigenmode) to extend the range of excitation frequencies for blade forced oscillation. Therefore, the current version of the steel blade is replaced by the versions made of laminate which offers more possibilities for increasing the torsional dynamic stiffness, even with possible optimization of its core structure.
