Minimizing Effects of Ground Vibration on Sensitive Equipment

There are three primary sources of vibration (noise) which can disturb a payload: ground vibration, acoustic noise, and “direct force” disturbances. Ground or seismic vibration exists in all environments throughout the world.

 

This noise has various sources, from waves crashing on coastal shorelines, the constant grind of tectonic plates, wind blowing trees and buildings, to man made sources like machinery, HVAC systems, street traffic, and even people walking.

 

Vibration isolation systems are designed to minimize the influence of these vibration sources. It is impossible to completely eliminate noise, but it’s possible to mitigate it. Many techniques have been used to mitigate ground vibration and its effect on sensitive instrumentation. In this guide we discuss the options available and the advantages and disadvantages of each technique.
