Determination of forces applied to vibration tillage induce at different oscillation amplitudes

Abstract

The purpose is to evaluate the effect of different oscillation amplitudes on the
magnitude of pulling force using induced vibratory tillage under field condition.
Arrangements of the oscillation amplitudes that are represented by eccentric
shafts in the vibrating plow were made and the angular velocity of the mechanism was measured using a tachometer (DT-2234C+). In the field, four replicates
for four treatments and a control evaluated, obtaining 20 replicates in which the
variables pull force (Fx), penetration (Fy) and torque (T) were measured, using a
flow regulating valve at 50% (4 Hz) to drive the vibration of the chisel. In each test,
40 m long lines made recording 2000 data at a recording frequency of 20 Hz, with
one-meter separation between each test line to avoid soil disturbance overlaps.
A 105 hp John Deere 6403 single traction tractor with a groundspeed of 2.8 km
h-1 and a LookBook 360 data acquisition system used. The completely randomized experimental design performed in Minitab software resulting in statistically
equeal axes. Therefore, it concluded that of the four axis evaluated, the axis with
an amplitude of 44.5 mm is the one that requires the least pulling force in this
study. The above without taking into account our control axis with an oscillation
amplitude of 50 mm, which exerts a lower pulling force than the other treatments.
