They show considerable potential in many applications, including vibration insulation, wave-guiding, noise control, and energy harvesting technologies. While the foundation of metamaterials research ...

Vibration testing and analysis. This has been referred to in a number of different ways, most of which are not meant to be complimentary. Voodoo box, black magic, rocket scientist stuff, etc. It is an ...

This course is designed to provide a theoretical background on the propagation of elastic stress waves in solids with periodic variation in geometry or elastic properties, a review of experimental ...

Disruption of a payload can be caused by three of the primary sources of vibration (or noise): ground vibration, acoustic noise, and direct force disturbances. Ground, or seismic vibration, is present ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

The vibration signature of a motor can tell you a lot about what’s going on. Entry level vibration testers can tell you the magnitude. If you have the training, you can use more sophisticated testers ...

A precision piezoelectric accelerometer incorporates a charge amplifier input stage for stability and minimizing errors. An integrated microcontroller operates under direction of a splashresistant ...
