Steel-ball device dissipates vibration to limit earthquake impact on buildings
The future of earthquake-proofing might just be a simple cylinder filled with steel balls.
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 ...
In analysis, it is common practice to conceptualize structures, objects, and isolation systems as basic mass-spring-damper models, as depicted in Figure 42.1. All objects experience vibration when ...
PORTLAND, Ore. — Angstrom-level accuracy is needed to stabilize platforms used in applications like microelectromechanical system testing, nanoscale metrology and semiconductor fabrication tools. One ...
Unlike conventional ball or roller-based linear guides, hydrostatic guidance systems eliminate all metal-to-metal contact. The guide carriages move on a thin cushion of high-pressure fluid, which ...
This article explains how adhesives and sealants improve connector reliability through moisture barriers, vibration damping, and mechanical stabilization.
