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 ...

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, ...

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 ...

Note: We are reprinting this article by Uncle Frank from our April, 1937, issue due to the demand we have had for back issues of this particular copy. Extra copies of this reprint are available by ...

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 ...

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 ...
