POSSIBILITIES OF REDUCING NOISE WITH SEGMENTAL BRAKE-BEAMS FOR RETARDERS

MOEGLICHKEITEN DER LAERMBEKAEMPFUNG MIT SEGMENTBREMSBALKEN BEI ZULAUFBREMSEN

The loud grinding noise which occurs during braking is largely attributable to the increased sliding friction coefficient in the lower speed range. This is represented with the existence of a "critical speed". A practical solution would be to get the "critical speed" below the usual working speed in the vicinity of the retarders, but during braking to a stop the noise could still occur. The most effective remedy could be segments made of materials which give almost constant dynamic and static friction coefficients when paired with steel. Using segments made of nodular cast iron, it was possible to determine the influence of the frictional coefficient under test conditions.
