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 ...

Large machines typically require attaching their frames or beds to a concrete foundation, often called a reaction or inertia mass. Equipment requiring isolation is ...

NOTE: Click on images or equations to make them larger. Last month’s column discussed the basics of simulating resonant or natural vibration frequencies as an introduction to performing advanced ...

Vibrations stem from a behavior that's inherent to all mechanical structures. Under load, all structures slightly deform and act springlike, causing motion to ripple to and fro as energy waffles ...
