Dynamic Analysis

- Extraction of natural frequencies
- Graphical representation of mode shapes

*natural mode shape of a turbine/generator-set foundation, calculated with cubical finite elements*

- Calculation of structural responses due to

- harmonic excitation (e.g. from rotor unbalances)

- impact excitation (e.g. from forging processes)

- transient excitation (e.g. from generator short circuit)

*time history of short circuit moment of a 650 MW-turbine/generator-set*

- Verification of the calculated figures with respect to permissible values issued by machine supplier

and specified limits according to national and international standards
