Isolated Foundations

Farrat boasts significant experience in the specification and supply of specialised isolated foundation systems.

Farrat Isolated Foundation Systems can be formed from: Isomat, VIDAM, Favim or Coil Spring and Visco-elastic Dampers depending on the machine or structure to be isolated.

Farrat Isolated Foundation Systems can be formed from: Isomat, VIDAM, Favim or Coil Spring and Visco-elastic Dampers. If provided with the nature of the requirement or the expected requirement, Farrat can provide technical / design advice and develop appropriate solutions including full specifications, predicted natural frequencies, damping ratios, layout drawings and installation instructions etc. If necessary site installation or supervision can be provided.

Isolated foundations are used to provide effective, low frequency isolation of machinery and equipment. They are used extensively in industrial applications either as Active Isolation to prevent noisy, vibration emitting equipment (power presses, printing presses etc) from disturbing their surroundings or as Passive Isolation to prevent sensitive equipment (body co-ordinate measuring machines, dynamometers etc) from being disturbed by structure born vibration.

Reasons for using isolated foundations:

increasing machine frame stiffness to maintain alignment during changes in applied static and dynamic loads
minimising changes in level due to alterations in static load distribution
increasing inertia mass of the machine and reducing vibration through mass damping
inertia blocks are usually 3 to 5 times the mass of the machine
lowering the centre of gravity to improve stability
distributing static and dynamic loads over a greater ground area
isolating low frequency of shock and vibration using more elastic Vibration Isolators than could be used between machine and foundation
low frequency disturbing vibration requires low frequency, high deflection vibration isolators. (On machinery requiring low operating motion amplitudes an isolated foundation is essential if low frequency vibration isolation is required).
