Most commercial vibration isolators have much lower horizontal stiffness than vertical stiffness. Constant-natural frequency isolators cost less than active damping systems and outperform conventional mounts.
The idea is simple: Protect sensitive objects from vibration. An object, modeled as a solid block, sits on a low-stiffness vibration isolator that, in turn, mounts on the vibrating support surface.
A company building relatively low-cost, steel-tube towers for wind turbines was able to lower the price of construction by 30%, but was having difficulty with large, transient wind loads shaking the structure.
Imagine driving down the highway listening to your favorite tune, when you catch a faint noise in the background. You turn down the volume only to hear a rattling noise.
