Prior to these, the state of the art in mistuning analysis is summarised and the theoretical background of the structural as well as the aerodynamical model employed in this work is illustrated. Consequently, the validation of the aeroelastic methods is presented at the example of the compressor likeStandard Configuration 10, a standardised test case of an aerofoil vibrating in a cascade, and the aerodynamical model is validated against bidirectionally coupled fluid structure interaction simulations of a 2D compressor rotor model. Finally, the aeroelastic behaviour of a mistuned blisk is analysed featuring measured mistuning patterns and extensive probabilistic analyses of mistuned blisk forced response. Die vorliegende Arbeit besch{\"a}ftigt sich mit der Analyse erzwungener Schwingungen von verstimmten Verdichterlaufr{\"a}dern unter Verwendung eines diskreten Ersatzmodells und aerodynamischen Einflusskoeffizienten. Zun{\"a}chst werden der Stand der Technik bezogen auf die Untersuchung verstimmter Systeme zusammengefasst und die theoretischen Hintergr{\"u}nde des verwendeten Struktur- sowie aerodynamischen Modells dargestellt. Im Anschluss daran werden die aeroelastischen Methoden anhand der Standard Konfiguration 10, einem standardisierten Testfall schwingender Schaufeln in einer Kaskade, {\"u}berpr{\"u}ft und das aerodynamische Modell mit Hilfe bidirektional gekoppelter Fluid-Struktur-Interaktions-Simulationen eines 2D Modells eines Verdichterrotors validiert. Schließlich wird das aeroelastische Verhalten einer verstimmten Verdichter-Blisk untersucht, wobei neben der Analyse experimentell ermittelter Verstimmungsverteilungen auch ausf{\"u}hrliche, probabilistische Simulationen durchgef{\"u}hrt wurden.}, language = {en} }
