Metodologia para redução do ruído em tratores agrícolas, sem o uso de cabines.

Abstract

The target this work was systematize a methodology for agricultural tractors noise level atenuation, without the cabin use. The method performs on two tractor noise source: the engine exhaustion system and the radiator airscrew cooling. The extent of reduction of noise should lower the noise to salubrious levels. The tests presents what a larger portion of a tractor original noise (more of 80 %) is of gas leakage. The project this equipment (his posição, os tubos, a câmara de expansão), presents how primordial item in this method.
