Abstrakt
The use of ploughing machine
-
and
-
tractor aggregates, operating according to the
principle of
‘push
-
pull’
, finds increasing application in the world since it allows ensuring the
stability of the movement and the depth of ploughing, reduction of the energy indicators. The aim
of this experimental study is to determine under field conditions the dynamic and ope
rational
technological parameters of the ploughing machine
-
and
-
tractor aggregate, operating according to
the
‘push
-
pull’
system. This aggregate was an integral ploughing
-
tillage wheeled HTZ 16131
tractor, in front of which there was mounted a two
-
bottom pl
ough, and at the rear
–
four
-
bottom
ploughs. This aggregate has satisfactory path parameters of the movement during the execution
of the technological process of ploughing. The oscillations of the furrow path for this aggregate
are of a low
-
frequency natur
e and are concentrated in a rather narrow frequency range (0...50
m
-
1
).
At the operating speed of 2.0
m
∙

it is 0...0.16
Hz. The maximum value of the
mutual correlation
function between the input impact (the turning angle of the driven wheels of the aggr
egating
tractor) and the output value
–
its relative bearing is positive and reaches a value of 0.88. Stability
of the ploughing depth for the aggregate according to the
‘2
+
4’
scheme is
±
1.65 cm
2
, which is
normally the smaller value of the same indicato
r for a serial ploughing aggregate (±
1.98
cm

).
