|Turbine Engines: Vibration Survey|
Explains the concepts of vibration, resonant frequency, Fourier transform, and multiples of run speed. Describes the relationship between displacement, velocity, and acceleration. Explains common causes of vibration at various multiples of run speed, the type of equipment and instrumentation used to measure vibration, and allowable or acceptable vibration limits. Explains how to perform, read, and interpret a vibration survey.
