Do you have a Bolted Connection?

Farrat offer several accessories to optimise isolation performance:

 

Farrat accessories be used in conjunction with Farrat vibration isolation and damping materials across a wide range of industrial applications, including but not limited to; Injection Moulding Machines, Hydraulic and Mechanical Machinery, Presses, Die-Casting Machines, Turret Punching Machines ,Packaging Machinery, Test & Measurement Machinery, Diesel Generators and Pumps & Compressors.

Note on Damping:

The prediction, measurement and behaviour of damping in elastomeric materials is much debated and, as you will see from our Farrat datasheets, varies with material type, strain, disturbing frequency, and amplitude.

Farrat have decided to use damping ratio, ζ, which, is the reduction in the vibration amplitude of a viscously damped system as a result of energy being dissipated as heat (converting of mechanical energy to heat). It is the ratio of the damping of the existing system to a damping necessary to make the system critically damped (ζ = C/Cc) and describes how vibration decays in the system after a disturbance.

In a hysteretically damped system, the equivalent viscous damping ratio at resonance is given by ζ=0.5η where η is the loss factor which is defined as the ratio of the energy dissipated during one cycle of harmonic displacement per radian to the maximum strain energy (stored energy) in cycle. Damping can be introduced into the system to control its response when resonance is not avoidable.

Our engineering capabilities allow us to help you choose the right vibration isolation materials for your application.

Our range of anti-vibration materials are manufactured in the UK and distributed worldwide across a wide range of industries. We are proud of the high performance these materials have provided our customers in their applications.

Material properties such as stiffness, dynamic stiffness, damping, load bearing capacity, shape factor, creep and hysteresis are continually tested in our R&D facility to provide an assured performance. We operate under an ISO 9001:2015 Quality Assurance System and under the international ISO 14001:2015 Environmental Management Standard.
