Modeling of rotating bladed disks by using conservative modal analysis
Abstract eng: The efficient method usable for the vibrational analysis of interacting flexible bodies is presented in this paper. It is motivated by the research of blades interaction in the framework of turbine bladed disks. The approach is based on the exporting system matrices, eigenfrequencies and eigenmodes for one blade from finite element software and assembling mathematical model in MATLAB system in an in-house code. The implemented code enables composing bladed disk model and more effective solution of dynamic problems including contact phenomena, prestress, etc.
