Vibration
isolation is a key element in CSA Engineering's vibration suppression
capabilities. Isolation is used to separate high vibration areas of a
structure or system from areas where significant vibration is not desired.
Vibration isolation is often a practical solution to vibration problems in
the case where transmission paths for vibrational energy can be identified
and physically modified. Vibration isolation is almost always more effective
at higher frequencies.
We apply vibration isolation in two general situations.
In the first, a quiet component is isolated from the rest of the system. In
the second, a noisy vibration-producing component is isolated. The result in
either case is the same: vibration transmission is modified to reduce the
vibration where it is least desirable. Examples of the first kind include an
instrument on a satellite or an inspection machine in a wafer fab. Examples
of the second kind include isolation mounts for noisy machinery, pumps or
motors.
CSA
designs vibration isolation systems for applications of all types. We
manufacture custom isolators and mounts subject to a variety of performance
and environmental constraints. In-house software tools allow rapid design
for multi-degree-of-freedom isolation. Detailed analysis is carried out when
necessary to understand dynamics that are far more complex than the
single-axis lumped mass model of vibration isolation contained in textbooks.
Test capabilities allow verification of isolator component properties and
measurement of effectiveness after installation.
Many of the isolation systems CSA designs and builds are
subject to unusual requirements. These may include vacuum compatibility,
thermal conductivity, or high performance at extremely low frequency.
Passive vibration isolators are more common and are usually adequate to meet
requirements. In cases where higher performance is required, CSA builds
active vibration isolation systems. These active systems, distinguished by
their need for power, are typically based on effective passive designs. The
active elements extend the isolation performance to lower frequencies or
reduce the vibration transmissibility significantly at specific frequencies.
Active isolation and suspension systems take advantage of CSA's expertise in
actuators, sensors, electronics, and digital control implementation.
