The article deals with the study of the influence of the
elastic damping mechanism (EDM) on the operability
index for arable MTU on the basis of the 1,4 class
tractor. The elastic damping mechanism was designed
in order to smooth the aggregate starting, to reduce the
dynamic load in transmission, to protect the engine
from the external load vibration. The experimental
results that were obtained while full-scale field studies
of serial and test (containing EDM in transmission)
machines are given in the article. Various oscillograms
are analyzed: torque on the axis of tractor's driving
wheel, tractive effort, the speed of the driving wheel,
angular velocity of engine shaft and haulage. The
mass-spectrum analysis was carried out to study the
tractor characteristics in time more thoroughly. Such
analysis allows to evaluate qualitatively the EDM
influence. The normalized autocorrelation function and
spectrum density of variation in time are studied in
details for the following MTU characteristics: the
wheel torque, haulage and tractive effort. These
characteristics were compared with analogous
characteristics for serial MTU model. The obtained
results confirm that the EDM use in the tractor
transmission has a positive effect on the functional
MTU indexes. Obtained data can be used in
mathematical modeling of MTU functioning
The article is devoted to finding of the optimum
parameters for elastically damping mechanism (EDM)
which is located in transmission of machine-tractor unit
(MTU). The investigated MTU is based on the tractor
of 1.4 class in plowing mode. EDM is designed for
MTU in order to make its’ start smoothly, to reduce the
dynamic load in transmission, to protect engine from
the external load vibration. The “transmittance level”
(index T) is used as evaluation of the protective
mechanism quality. The study was carried out by
means of the experiment planning method, viz. the
central composition plan of second order with five
factors. A regression model for response function
(“transmittance level”) is given. This model takes into
account the chosen EDM characteristics. The statistical
analysis methods (Student’s t-test, Fisher’s test) were
used to study the regression model. The dependence of
response function on each factor apart, their cross
impact on the process are described. The system of
partial differential equations is obtained to find the
optimal values of parameters and response function.
The optimal value of a “transmittance level” can be
obtained by varying different EDM parameter values.
Optimal values of parameters and as result - response
function - allow improving of MTU functioning in
plowing mode
The article is devoted to mathematical modeling of random process that occurred in tensile load of serial and experienced MTU. The efficiency of EDM application in transmission is discussed
