Abstract

MARIN CABRERA, Luis Orlando; LEYVA SANTIESTEBAN, Osvaldo  and  HERRERA SUAREZ, Miguel. Effect of the vibration mode and forward speed in the reduction of draft force in the vibrating scarifies. Rev Cie Téc Agr [online]. 2011, vol.20, n.3, pp.57-62. ISSN 2071-0054.

This paper aims to analyze the effect of the vibration mode and forward speed in the reduction of the draft force in the vibrating scarifiers. To complete this objective the experimental research was develop in the areas of production of Agroindustrial Complex Sugar "Boris Luis Santa Coloma", belonging to the town of Madruga, Mayabeque province, where they analyzed the effects of self and forced vibrations (factor A) in the tensile strength of a prototype vibrating scarifiers. (Bayamo 81M). Also analyzed the effects of the forward speed (Factor B) in the draft force demand. The results showed that of these factors, the type of vibration exerted a significant influence on the variability of draft force, the forward speed effects was not found significant, as well as the interaction between both factors. Although was not significant the effects of speed, when exhibit values of 4,5 km/h the effects on the variability of draft force were higher than for the speed range of 1,044 to 3,96 km/h. Similarly it was found that the use of forced vibrations in scarification depth allows a reduction in draft force by nine percent, compared with the use of self vibrations.

Keywords : prototype; self; forced; vibration.
