The internal structure of many aero-engines is designed with a dual-rotor system. Up to now, there have been few studies on the influence of aerodynamic excitation on the dual-rotor system. The ...

On the technology spectrum, railroads would certainly seem to skew toward the brutally simplistic side of things. A couple of strips of steel, some wooden ties and gravel ballast to keep everything in ...

Applying vibration modelling in gas turbines to fault monitoring of the same equipment can assist maintenance planning and extend system life. Bearings are responsible for vibratory phenomena in gas ...

Nothing runs as smooth as a new machine. After time, as components wear, the hum of productivity becomes the whine of a tired collection of loose fitting parts beating out of unison. This condition is ...

Rolling bearings are essential components in automated machinery with rotating elements. They come in many shapes and sizes, but are essentially designed to carry a load while minimizing friction. In ...
