Resumo: The objective of this study was to evaluate the noise and vibration levels of a mechanized tractor-sprayer set, in function of the working speed. The work was conducted in the Laboratory of Agricultural Mechanization, Department of Agricultural Engineering, Universidade Federal de Viçosa - MG. To determine the levels of noise and vibration transmitted to the body of the operator a dosimeter model Wed007 was used, manufactured by 01dB in Brazil and one triaxial accelerometer model Maestro, respectively. The working speeds used were 4.0, 5.0 and 7.0 km h-1. The results obtained for the noise levels were 98.2 dB (A) for the speed of 4.0 km h-1, 98.1 dB (A) for 5.0 km h-1 and 97.4 dB (A) for 7.0 km h-1. In the vibration analysis the results were 0.58 (4.0 km h-1); 0.60 (5.0 km h-1); and 0.60 (7.0 km h-1) m s-2. According to the results it was concluded that all noise levels were superior to the established standard NR-15 of 85 dB (A) for a work shift of 8 hours per day, and increased speed resulted in reduction noise levels. The vibration of the tractor-sprayer showed values above the thresholds set by the European Directive of 0.5 m s-2 at all speeds evaluated, also being influenced by the forward speed of the mechanized set.

O trabalho foi conduzido no Laboratório de Mecanização Agrícola, do Departamento de Engenharia Agrícola da Universidade Federal de Viçosa – MG. Para determinação dos níveis de ruído e vibração transmitida ao corpo inteiro do operador foram utilizados um dosímetro modelo Wed007, fabricado pela 01dB do Brasil e um acelerômetro triaxial modelo Maestro respectivamente. As velocidades de trabalho utilizadas foram de 4,0; 5,0; e 7,0 km h-1. Os resultados obtidos para os níveis de ruído foram 98,2 dB (A) para a velocidade de 4,0 km h-1, 98,1 dB(A) para 5,0 km h-1 e 97,4 dB(A) para 7,0 km h-1. Na análise da vibração os resultados encontrados foram 0,58 (4,0 km h-1); 0,60 (5,0 km h-1); e 0,60 (7,0 km h-1) m s-2. De acordo com os resultados, concluiu-se que todos os níveis de ruído encontrados foram superiores ao estabelecido pela norma NR-15 de 85 dB(A) para uma jornada de trabalho de 8 horas por dia, sendo que o aumento da velocidade culminou na redução dos níveis de ruído. A vibração do trator-pulverizador obteve valores acima dos definidos pelos limiares da Diretiva europeia de 0,5 m s-2 em todas as velocidades avaliadas, também sendo influenciada pela velocidade de deslocamento do conjunto mecanizado.Universidade Federal de Viçosa - UFV2014-04-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/42410.13083/reveng.v22i2.468Engineering in Agriculture; Vol. 22 No. 2 (2014); 112-118Revista Engenharia na Agricultura - REVENG; v. 22 n. 2 (2014); 112-1182175-68131414-398410.13083/reveng.v22i2reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/424/304Santos, Larissa Nunes dosFernandes, Haroldo CarlosSouza, Amaury Paulo deFurtado Júnior, Marconi RibeiroFigueiredo Silva, Remo Macieirainfo:eu-repo/semantics/openAccess2023-01-19T13:21:40Zoai:ojs.periodicos.ufv.br:article/424Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:21:40Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
