What is ODS Analysis of Fan Vibration Issues about?

The document describes a case study where high vibration was observed in an industrial process fan. An operational deflection shape (ODS) analysis was performed which identified that the fan pedestal and frame were resonating due to an inadequate number of anchor bolts and deteriorated grout. Additional structural elements and anchor bolts were installed along with grout repair, reducing vibration by 85%. The ODS analysis clearly showed the flexing of the fan frame and helped communicate the problem to mana
