Calculation Substantiation of the Parameter Values Determining the Traction Properties of a Uniaxial Mobile Pushing-Type Power Vehicle

Abstract

The aim of the work is to study the static parameters of a pushing unit based on a uniaxial mobile power vehicle (UMPV). The article gives the analysis of the influence of the parameters of ballasting and traction load on the reaction of the wheel, the reaction of the support heel of the plow, the weight distribution coefficient, the force on the control handles. Using the MATLAB software, a computer model is implemented that makes it possible to take into account the influence of various parameters of the pushing unit when they change on its static indicators. It is found that in a pushing unit based on the UMPV, a growth in the weight of ballast loads Gб increases the loading of the driving wheels, improving the traction properties of the unit compared to the traction unit based on the UMPV. It is shown that increase in the traction load Rx and the distance aн to agricultural equipment leads to an increase in the load on the driving wheels and control handles, the weight of ballast loads is 0.07...0.35 kN, which is less than that for a traction unit based on UMPV (0.1...0.45 kN).
