Abstract
The article shows one of the ways to evaluate the “machinetractor unit” system using a statistical model from the point of view of reducing non-productive rolling losses. The necessity of making structural changes in order to reduce the filtering capacity of the MTU system for high-frequency perturbations is justified.
Highlights
It is known that the shifting of the energy spectrum of traction (Ркр), as well as the spectra of torque (Мкi) in the area of frequency (10-12 c-1) allows to improve traction and dynamic performance of the power unit and quality characteristics of the performed technological processes, including for plowing
There is a need to assess the filtering capacity of the machine-tractor unit (MTU) system based on the frequency of Ркр and Мкi and to find the transfer function of this system to determine the involuntary rolling losses
In connection with the task of studying unproductive rolling losses of the MTU as an input parameter, it is advisable to take the tractive resistance of an aggregated agricultural machine or a tool (Ркр), and as output parameters – torques on the half-axes of the energy unit (Мкi)
