Experimental characterization of an axial compressor’s casing vibrations

The influence of casing and foundation structures is insufficiently considered in rotordynamics models. Casing structures can have an influence on the natural frequencies and the damping of rotors. For this reason, a joint research project between IDS and TFD yields a nonlinear, reduced casing model, which is validated on the basis of experimental data. To this end, experiments are carried out at TFD both at standstill condition, in particular with the aid of electrodynamic vibration exciters and numerous accelerometers, and during operation of the high-speed axial compressor. Methods used to determine the modal parameters include experimental modal analysis and, for the data from operation, operational modal analysis, which is as well further developed. The experimentally validated casing model will serve as input for rotordynamics models and will improve their predictions in the future.
