Rotating equipment analysis

Rotating equipment analysis is another vibration monitoring tool used to assess the general mechanical health of rotating and reciprocating machinery.

Waterfall plots and order tracking are commonly used to quantify operational characteristics and the critical speed of rotating machinery. Frequency response testing is used to determine the machine's structural characteristics.

Rotating equipment diagnostics identifies rotor imbalance, mechanical looseness, bearing defects, motor mechanical and electrical problems, shaft misalignment, gearing faults, and foundation problems. Operational deflection shape analysis is used to determine the structure's forced vibration shape. Employed techniques also identify if detrimental resonances exist in the equipment, support structure, or foundation. Modal analysis can then be used to visualize the associated patterns of structural deformation.
