Rotor Modeling
Thru the years, we have learned
now, how to efficiently model your rotor. And its support
substructure.
This is a complex gas turbine rotor, which required
special mathematical reduction techniques in order to fit it to
computer codes. A thermal gradient was also required, together with
differential pedestal flexibility.
An experimental modal analysis allowed to validate this rotor
model, in two ways: mode shapes and natural frequencies. 2% error
was achieved.
