High speed turbomachinery necessitates a thorough understanding of the machines lateral and torsional rotordynamic behavior to ensure long term safe and reliable operation. Not only is this essential when specifying, or procuring new equipment, but it is also important in any machinery re-rates, or rotating equipment component upgrades. Becht engineers are intimately aware of and share the end-users concerns about ensuring safe, predictable machine behaviour and high reliability.
Becht offers both review of OEM and 3rd party lateral and torsional rotordynamics analysis, but also offers in-house rotordynamic analysis capability, based on client need. In our experience, an independent lateral and torsional rotordynamic analysis is often the only way to identify errors or oversights in the vendor’s analysis, which are not uncommon. Overlooking turbomachinery rotordynamic behavior, or incomplete/incorrect rotordynamic analysis can result in a protracted “crisis” situation, which is often not readily corrected without major re-design. The resulting schedule delays and lost production can adversely limit plant operation and project profitability. Close attention to machine lateral and torsional rotordynamic behavior is essential to achieving trouble-free reliable high speed machinery operation.
