Power Press and Draw Bench Noise Control – via vibration dampers

Power press vibration damping noise control

The noise from this 115T Bliss power press was reduced by 90% (10dB) by analysing the flywheel vibration and then bolting £15 worth of small steel blocks mounted on gasket springs at specific points. These tuned dynamic vibration dampers cancel out the flywheel vibration, fit inside the existing guards and were installed in a few hours. Compare this with the cost and access problems associated with the only alternative noise control measure – a high cost conventional acoustic enclosure.

Similar dynamic vibration dampers fitted to the main gear wheels on a wire draw bench reduced the overall noise by 5dB(A) – again with no effect on normal operation, access or maintenance and at a cost saving of c £13000.
