This work provides an integrated approach developed with the aim of reducing the noise of generating sets, and the results obtained. The methodology and the procedures employed, with the indications obtained from theoretical analysis, are extendable to a vast range of industrial machines.

Abstract

This work provides an integrated approach developed with the aim of reducing the noise of generating sets, and the results obtained. The methodology and the procedures employed, with the indications obtained from theoretical analysis, are extendable to a vast range of industrial machines. The approach described has been applied to some PRAMAC Lifter generating set, presenting a high value of sound power, in order to reduce it accordingly with the value provided by the recent normative. Two production series generating sets were examined. The first, named S 12000, is a petrol engine generating set, with a 10,8 KVA alternator power and 614 cm3 of cubic capacity; the second, named S 6000, is a diesel engine, with a 5,5 KVA alternator power and 406 cm3 of cubic capacity. The implementation of the method described in the paper concerns the design of a new frame for the two machines and the development of new acoustical muffler.
