The modeling of defects in the rotor-trains of turbomachinery – simulation-based diagnostics
Abstract
The problem of the turbomachinery defects modeling is considered. The numerical analysis of the proper model and its defect can give the symptoms of the defect. The presented computer software MESWIR can generate the kinetoststic characteristics of bearings and vibration of the entire system (the shaft and the bearings), that allow carry out model-based diagnostics of a several classes of defects. A large power turbo-set is taken for example calculations. A two different defects were modeled: the bearing misalignment and the crack of the shaft.
