Vibration
control in vibration-sensitive advanced technology facilities generally involves
interaction between a vibration consultant and several other engineering disciplines.
It is important that the other disciplines have a rudimentary understanding
of the consultant's measurement methodologies and design approaches. Practitioners
have developed a specialized analytical approach which shares some commonality
with traditional civil engineering dynamics, but which also borrows techniques
that evolved in other disciplines such as mechanical engineering, signal detection,
and acoustics. Practitioners also use several forms of spectral representations
of the low-vibration environment, but the spectrum form most familiar to civil
engineers the response spectrum is not used.
This paper presents some of the relevant fundamentals of signal processing
and the manner in which they are applied to civil and structural engineering
aspects of these projects.
