Your engine is supposed to vibrate, just a little. But when the shaking gets harder to ignore, there’s probably something ...

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, ...

Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences, Vol. 292, No. 1431 (Jun. 14, 1966), pp. 537-561 (27 pages) The results are given of experimental and ...

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 ...

Reducing energy consumption and eliminating downtime has never been more important than in today’s energy cost-conscious and highly competitive industrial environment. Whether generating power, ...
