What Floor Vibration Will a Machine Produce

Eric E. Ungar, Acentech, Inc., Cambridge, Massachusetts
The Problem
In an often-encountered situation, a
vibration-producing machine is to be
moved from its present location to a new
one without changing how the machine
operates and one wants to predict the
expected vibrations of the floor in the
new location. If the floor structures are
the same at the machine’s present and
new locations, then the vibrations that the
machine will produce in its new location
will be the same as those it produces in
its present location. But what if the floor
structures at the two locations differ
