Tiny generators could produce enough electricity from random, ambient vibrations to power a wristwatch, pacemaker or wireless sensor.

In addition to only random or only sinusoidal vibration testing, specifications call for different combinations such as sine-on-random, which is suitable for testing vehicles.

Options include exploiting random vibrations or motions (such as those near a roadway), temperature gradients (for example, ground temperature is fairly constant several meters below the surface ...

Last month’s column discussed the basics of simulating resonant or natural vibration frequencies as an introduction to performing advanced vibration analysis. Here, we delve deeper into random ...

Courtesy of LDS-Dactron One alternative is to abandon random testing completely and instead test by rerunning actual recorded vibration test data. For example, rather than use a predefined ...

Some Galaxy Watch 7 and Ultra owners are experiencing random vibrations with no notifications attached. It appears there’s more than one cause for the phantom vibrations. Turning off certain ...
