Modeling the towing properties of construction vehicles

Abstract

Abstract This article studies the ways to increase the towing properties of propulsors and the patency of wheeled vehicles. The characteristics of the machines running systems significantly affect the technical level of the unit. The paper justifies the advantages of wheel dwellers over caterpillar ones. The advantages include small specific metal consumption and the possibility of usage on the roads. Wheel tractors provide the best working conditions for the driver and maintenance personnel. Analysis of the calculated coefficients shows a significant scatter of values, which causes difficulties in the calculations. For this, it is necessary to know the values at each interaction of the tractor propulsor with the soil. The same slippage values can be obtained with different values of the coefficients. The task is simplified if these dependencies have one coefficient. The paper obtains a model for a more complete assessment of the towing properties of wheel and tracked vehicles with a minimum number of experimental coefficients, which makes it easily applicable for engineering calculations.
