The severe vibrations aboard rockets, spacecraft, and satellites en route to orbit and those less severe but sometimes troublesome of military and commercial aircraft (especially helicopters), ...

Vibration testing helps to predict how well a product will withstand its intended service or transportation environment. Some new vibration controllers have the capability to replicate data recorded ...

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 ...

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 ...

MOTION CONTROL: PCB Piezotronics Inc. announced Model 352B70, the newest sensor in the family of accelerometers designed for extreme testing found only in shaker labs. PCB has worked closely with ...

Traditional isolators are built with metal springs or rubber blocks. They have low internal damping and generally are only effective at frequencies near 10 Hz. They also offer little to no isolation ...

Traditional isolators are fabricated using metal springs or rubber blocks. They have low internal damping and only tend to be effective at frequencies in the region of 10 Hz. They also fail to isolate ...
