dc.description.abstractVibration caused by resonance is an industry problem for new and retrofit applications that persists due to lack of specification and upfront analysis. To limit the chances of resonant vibration, dynamic analysis of the structure and rotating assembly to evaluate structural, rotor lateral and rotor torsional frequencies is done when the pump installation “warrants” it. However, dynamic analyses take time, require expertise, and cost money: It is not always clear when a pump is purchased if the installation warrants the expense of analysis. Furthermore, the purchaser may not know what type and levels of dynamic analysis should be specified. This results in poor specification, missed specification or specification of analysis when it is not needed. ANSI/HI 9.6.8 Rotodynamic Pumps – Guidelines for Dynamics of Pumping Machinery is the first American National Standard to cover this topic; it provides methods to evaluate the risk and uncertainty of a pump installation. A standard specification template is provided to aid the user. This tutorial will address the issue of resonance, review the importance of the guideline, how to apply the guideline, and risk factors, levels of analysis and methodology. Case studies are also provided.
