PORTLAND, Ore. — Angstrom-level accuracy is needed to stabilize platforms used in applications like microelectromechanical system testing, nanoscale metrology and semiconductor fabrication tools. One ...
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 ...
Call it what you will — resonance, looseness, vibration, shock load, backlash, imbalance, noise, or strain cycles — none of it is good for machinery and equipment, leading to premature aging, unsafe ...
