Uncertainty treatment in forced response calculation of mistuned bladed disk
Mistuning, imperfections in cyclical symmetry of bladed disks is an inevitable and perilous occurrence due to many factors ncluding manufacturing tolerances and in-service wear and tear. It can cause some unpredictable phenomena such as mode splitting, ode localization and dramatic difference in forced vibration response. In this paper first, a method is presented which calculates he forced vib...
متن کاملForced response of mistuned bladed disks using reduced-order modeling
A reduced-order model formulation is presented for examining the forced response of tuned and mistuned bladed disks. The technique developed uses modal information obtained from highly detailed finite element models to create, in a systematic manner, much simpler and computationally inexpensive models of bladed disks. The small size of the reduced-order model and associated computational saving...

متن کاملUncertainty quantification for an industrial mistuned bladed disk with geometrical nonlinearities
Recently, a methodology allowing a stochastic nonlinear reduced-order model to be constructed in the context of the nonlinear mistuning induced by geometric nonlinearities has been proposed. The present work is devoted to an industrial application for which the centrifugal stiffening due to rotational effects is also included. The nonlinear mistuned forced response is investigated in the time-d...

EXPERIMENTAL INVESTIGATION ONMISTUNEDBLADED DISK SYSTEM VIBRATIONbyJia Li Co-Chairs: Christophe Pierre and Steven L. Ceccio Bladed disks are critical structural components in jet engines and other turbomachin-ery. The nominal design for a bladed disk is typically assumed to have identical blades.However, there are always small, random variations in the blade properties d...
