Dependência Espacial Do Ruído De Tratores Agrícolas Em Diferentes Rotações Do Motor

Abstract: Diversos elementos afetam a saúde do trabalhador, sendo o ruído um importante fator causador de estresse e prejudicial aos operadores expostos por muitas horas à tais ruídos elevados. O objetivo do trabalho foi de quantificar e dimensionar a amplitude dos valores de ruído em diferentes rotações de dois tratores agrícolas. O ensaio foi realizado nas dependências do Núcleo de Ensaio de Máquinas e Pneus Agroflorestais, Faculdade de Ciências Agronômicas, UNESP de Botucatu/SP. O ruído foi mensurado com um decibelím… Show more

“…Thus, from this distance onwards data will have a random spatial distribution, becoming independent of each other (Missio et al, 2015). Spadim et al (2015) also found spatial dependence for agricultural tractors working at different engine speeds, but with a minimum range of 22.89 m. We observed a nugget effect (C0) of 0.10 (Table 2), which presupposes the absence of analytical errors, sampling errors, or natural effect of the studied phenomenon; therefore, data collection for analysis was suitable (Lundgren et al, 2015).…”

“…It should be emphasized that most of the studies that evaluated the noise produced by agricultural machines using geostatistics conformed to the Gaussian model (Pimenta Junior et al, 2012;Yanagi Junior et al, 2012;Missio et al, 2015;Spadim et al, 2015). Ferraz et al (2013) analyzed the noise of portable coffee harvesters and assembled the spherical model.…”
