2.2 Harmonic Analysis
Based on the results from modal analysis the critical location was determined and the
response on the harmonic excitation was evaluated. The excitation of the structure
was performed by modal exciter placed in bearing location. The force direction was
determined based on the gear contact, the force amplitude is constant with increasing
frequency. For that reason, the results are usable for comparative study. The results
of harmonic analysis are shown in Fig. 2 for different frequencies.
