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 ...

We have learned that an effective way to passively control vibration is through the usage of a “vibration absorber”. A typical vibration absorber is a single-DOF spring/mass/dashpot system that is ...

A three dimensional seismic isolation system was developed and experimentally validated for high-voltage electric power transformers of weight in the range of 300 to 800kip. Although the validation ...

In recent decades, several theoretical approaches have attempted to quantitatively predict magnetic damping in metallic systems. One of the early promising theories was that of Kambersky, who ...

Actual automobile crash scenarios include "wheels-first" landings after the vehicle leaves the road surface and becomes momentarily airborne. These events generate a vertical acceleration vector in a ...

Imagine holding a yardstick at one end. When you flex your wrist even the tiniest bit, the far end of the yardstick whips back and forth. But if you hang a small weight on a spring at that far end, ...
