Examples

Resonance elimination
- - calculation of component or assembly natural frequencies. The target is to tune the structure so that the natural frequencies are away from excitation frequencies.
Response to forced vibration analysis
- - response analysis to the forced vibration identifies critical locations which are further evaluated according to applicable requirements.
Seismic qualification
- - Components qualification to a seismic loading according to appropriate Code. Dynamic analysis provides
