What is modal analysis? Evaluating vibration sensor enclosures and their natural frequencies. Determining the most important modes and frequencies with the mode participation factor. A close look at ...

In the last issue of MACHINE DESIGN, we examined methods to predict how vibration-isolation systems would perform. (“Shaking up vibration models,” Nov. 6, 2008, p. 63 to 68.) This discussion centered ...

Multipath makes it difficult to detect very low-frequency structural vibrations, ranging from 0.05 to 1 Hz, important in characterizing dynamic loads and determining safe structural lifetimes. The ...

When bridges and buildings begin to vibrate, whether from the wind or traffic or another stressor, they can literally shake themselves to pieces. Watch a 1940 clip of the Tacoma Narrows Bridge ...

In the event of a breakdown, any number of issues may be the culprit, but there’s one in particular that’s particularly challenging to diagnose: resonance. Resonance can be a problem in any machine, ...

Erik Runge, Director of Engineering at Minus K Technology, talks to AZoNano about their low-frequency vibration isolation systems. Could you provide our readers with a summary of the history of Minus ...

Ground vibration testing of DLR's D328® UpLift research aircraft has been successfully completed. The data will be used to validate and improve the aircraft's simulation model, to enable faster and ...
