The operational motion analysis of structural deflection can be assessed through an Operational Deflection Shape analysis (ODS) in order to find proactive solutions in solving structural weaknesses or excessive vibrations. Additionally, an easy relation between component failures and machine operational motion can easily be found.
If any resonances are occuring, ODS analysis can pinpoint the exact adaptions needed in order to avoid any mode shape excitation to interfere with the operational machine behavior. If not possible, the resonance ranges and corresponding mode shapes may as well be mapped in order to program an operational speed area to be avoided.
