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 ...

Increasing train speeds and greater axle loads on the rail lines of today has correspondingly increased the harmful impact of noise and vibrations on the areas around rail lines. The unevenness that ...

• Negative-stiffness isolators use mechanical components to keep vibrations from sensitive equipment. • Negative-stiffness systems’ 0.5-Hz resonant frequencies give them better low-frequency isolation ...
