Analysis of essentially non-linear vibration of large-scale models for bladed discs with variable contact and friction at root joints
An effective method has been developed for analysis of the multiharmonic forced response of large-scale finite element models of bladed discs with contact interfaces at blade roots. Area contact elements are developed to model nonlinear forces acting at the contact surfaces. The elements allow for unilateral normal and tangential friction contact forces. The friction model includes effects of the variable normal load and variation of the contact area. Numerical investigations of the forced response for realistic finite element models of bladed discs with root damping are performed for the first time
