Title Quietening circular saws by reducing blade vibration
Bibliographic information July-Aug. 1989, Vol.33, No.1, p.33-37. Illus. 6 ref.
Abstract A series of experiments was undertaken to reduce the laterally-induced forced vibrations which radiate noise from a circular saw when cutting. Two dampers in the form of flat plates supported by air bearings were placed on each side of the blade beneath the saw table. Using semicircular plates, a reduction of 16dB was achieved; using more economical circular plates the reduction was 6 to 8dB. Best noise reduction was achieved for very small gaps (0.1mm) at plate porosities of 0.05 to 0.075 percent and at flow rates of 80 to 130L per minute through the porous plates.
