6. Industrial applications
Predicting the dynamic behavior of rotors requires modeling that is as close to reality as possible. Particular attention must be paid to the modeling of assemblies, and where possible, it is advisable to recalibrate the rotor modeling without bearings. In the case of the 6.2 turbo-compressor, a frequency response was carried out, enabling us to improve the modeling of the turbine disk.
The stiffness and damping characteristics of bearings, in particular bearing damping, are difficult to know. The damping introduced by the assemblies is taken into account in the software via modal damping,...
