Investigation of the model for transient beating phenomenon in symmetric structures with Braille elements

Results of experimental investigations of vibrations of a circular plate under impact loading are presented. In such structures when there are small defects causing non-symmetry, such as Braille elements, transient beating phenomenon is observed. Simplified mathematical model for the investigation of this experimentally determined transient beating phenomenon is proposed and numerical results based on this model are obtained and investigated. From the presented results qualities of the envelope function in the investigated transient beating phenomenon are determinedKauno technologijos universitetasSistemų analizės katedraVytauto Didžiojo universiteta
