Overhead electrical distribution lines are traditionally constructed with bare aluminum or copper conductors energized at thousands of volts. This presents a danger to people and wildlife from ...

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 ...

(Nanowerk Spotlight) All mechanical systems exhibit vibrational resonances, where energy transmission through the structure spikes at certain natural frequencies. This resonance effect stems from the ...

When in doubt, make it stout. That was the rule of thumb for designing strong and durable machine tools in the past. Over the years, however, this mindset has changed as technical advances have ...

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 ...
