Details:
Half-day (4-hour) interactive workshop
Exact time: 12:00PM to 5:00PM
Description:
Often vibration analysis uses the response of a machine to dynamic forces to determine condition and faults. This workshop will describe fundamental aspects of vibration, why it is measured, how it is measured, how it is used to evaluate machinery, why vibration analysis can be difficult to master, factors that complicate vibration analysis, and characteristics of specific machines such as centrifugal pumps and electric motors.
Examples of faults and solutions will be provided. Subjects such as structural resonance, BB3 pump cross-over acoustic resonance, vane-pass, cavitation, mechanical faults, off BEP (Best Efficiency Point) operation, ball bearings, electric motors, vertical pumps, finite element modeling, and fluid whirl/instability will be discussed. Solutions to problems including resonance resolution through structural changes or damping will also be presented.
Tools and techniques will be presented to optimize data collection; modal testing, motion amplification cameras, multi-channel analyzers, and ODS/Modal animations. Many years of experience, failures, and successes will be shared to help the analyst become more efficient and effective with practical vibration analysis. The strengths and weaknesses of vibration analysis will be discussed; vibration is one of many tools and sources of information needed to make a good analysis and conclusion regarding machinery faults and condition.
