Industrial noise and vibration control pdf

Cork plays a significant role in the elastomer and is directly responsible for the damping function, commonly designated as the energy loss factor, while the rubber matrix takes care of the isolation, together they are the ideal combination when considering vibration and noise reduction solutions especially at resonance frequencies. The elastomeric blend is distinctive to rubbers which are incompressible, needing space to displace the compressed volume, cork rubber displaces much less volume due to corks compression within itself allowing for a wider tolerance in part shape and dimensions commonly designated as the shape factor, which in turn affects the design robustness. Amorim VC vibration control material is especially used in power transformers and reactors as vibration pads beneath the active part immersed in oil, as well as decoupling supports between the core structure and the tank wall or tank cover on the core clamping mechanism. VC appropriately applied is able to reduce up to 6dB in overall transformer noise. A number of different options are available to the power industry for external vibration pad materials.

Failure to select the proper product may result in either equipments damage or personal injury.

Noise control and vibration control treatments are not one-size-fit-all solutions. Different control mechanisms and strategies should be used to solve different problems.
