Vibration monitoring and analysis are a cornerstone for determining the condition of rotating equipment. But of all the common testing technologies available (ultrasound, infrared, electric motor ...

A steering wheel that vibrates at highway speeds is most commonly caused by wheels that are out of balance, tyres with uneven wear, or front suspension components that have developed play. The ...

The convenient and non-contact mapping of operational deflection shapes is a specialty of Polytec's Laser Scanning Vibrometers. With Polytec's new Optical Derotator now also rotating objects such as ...

Effective monitoring of slow speed rotating industrial applications, such as wind power generation and hydro-electric turbines is a critical requirement, just as it is on standard speed applications, ...

A ROTATING shaft can exhibit torsional vibration when, because the dynamic coefficient of friction is less than the static value, the frictional force at the bearings supporting the shaft decreases as ...
