| contents | Vibration levels on rear and front axles of a tractor in agricultural operations Geice Paula Villibor Fábio Lúcio Santos Daniel Marçal de Queiroz Denis Medina Guedes Ingeniería forward speed Tillage operations mechanical vibrations Excessive vibrations in agricultural tractors can contribute with mechanical failures and subject the operator to discomfort. This work evaluated the vibration levels on rear and front axles of an agricultural tractor working at different forward speeds and wheel drive conditions in plowing and harrowing operations. Field tests were carried out in a completely randomized design in a factorial arrangement 3 x 2 (forward travel speeds x front-wheel-assist enable or disable), with three replications. Tractor vibration was measured using two single axis accelerometers fixed above the rear and front axles. The actual forward speed of the tractor was obtained by means of ultrasonic radar and the angular velocity of the wheels was measured with magnetic transducers. The drawbar force to pull the disc harrow was obtained by a load cell. The results showed that the vibration levels observed for the plowing operation were higher than observed for the harrowing operation. When the front-wheel-assist (FWA) was enabled there was a reduction in vertical vibration levels of the tractor axles. The highest vibration levels were observed in the frequency range of 2 to 4Hz for the both soil tillage operations evaluated. Keywords: tillage operations, mechanical vibrations, forward speed. 2014 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303229336002 en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
