Effect of the dry friction damping structure on the localized vibration of mistuned bladed disk
In order to study the effect of the dry friction damping structure on the localized vibration of mistuned bladed disk, the forced vibration response of a mistuned bladed disk with dry friction damping structure is investigated by using three-dimension microslip friction contact model which could rep...

In order to study the effect of the dry friction damping structure on the localized vibration of mistuned bladed disk, the forced vibration response of a mistuned bladed disk with dry friction damping structure is investigated by using three-dimension microslip friction contact model which could reproduce the characteristics of local micro-motion slip and anti-aliasing hybrid frequency-time domain method. The variation of blade vibration response and the change of localization factor are compared with considering dry friction damping at the blade shroud and not considering dry friction damping. And the influence of the dry friction damping parameters on the vibration control of mistuned bladed disk system is discussed. The results show that the dry friction damping structure can reduce the degree of localization of the vibration response of the mistuned bladed disk system, the friction force between the blades is completely different, and the optimal initial normal pressure and the optimal friction coefficient for each blade are different. Therefore, the effect of the dry friction damping structure to each blade of the mistuned bladed disk is different, and the vibration reduction design of the mistuned bladed disk needs to consider the matching relationship between control parameters and mistuned blade. |
