In vibration-critical applications, understanding how a PCB deforms under excitation is essential. Using massively parallel ...

Step aside windmills, there's a new way to harvest kinetic energy in the works. A research team at the Ohio State University has created electromechanical devices that look like tiny leafless trees ...

Random vibration testing provides energy simultaneously at all frequencies. Vibration testing can help ensure that your new design will survive its intended environment. The problem is knowing how ...

Many readers probably think “black magic” describes the math involved in finding the dynamic response of a structure from random excitation. When can you be sure you have jumped through all the ...

ANN ARBOR, Mich.---Tiny generators developed at the University of Michigan could produce enough electricity from random, ambient vibrations to power a wristwatch, pacemaker or wireless sensor. The ...

Many shaker controllers for random vibration testing are based on the well-established FFT data processing algorithm. A test specification is given in the frequency domain in terms of power spectral ...

Mr. Neill Doertenbach, Senior Applications Engineer, of Qualmark Corporation originally prepared this research paper for the 2014 RAMS conference. The classic ED vibration system has been used for ...
