Many serious machine problems can be diagnosed early with normal vibration analysis techniques based on fast Fourier transforms. But some problems remain dangerously hidden in the vibration reading — ...

Vibration calibration and measurement techniques are critical for ensuring the accuracy and reliability of sensors and instrumentation employed in diverse fields such as civil engineering, seismology, ...

Aircraft structures are prone to vibrations due to their lightweight construction. In most cases, these vibrations are not critical. They decay due to damping effects from aerodynamic forces and ...

How do you use vibration analysis in your maintenance shop? The answer from the typical shop would be something like: “We check motors during a PM to see if they have balance issues.” That’s typically ...

There's typically no way around it. At some time during a motor's life, it is likely to experience high vibration levels. What's behind this maintenance phenomenon? The cause may be an electromagnetic ...

Renown Electric Motors & Repairs Inc., a leader in electric-motor services based in Ontario, Canada, has announced updates to its electric motor vibration analysis services. The company continues to ...

Engineers looking to improve their understanding of vibration and how it affects mechanical equipment may want to consider taking a four-day course presented Engineers looking to improve their ...

In this work, we discuss statistical energy methods for predicting mid-frequency vibration transmission between two spring-coupled substructures with parameter uncertainties. We adopt a ...
