Abstract

The issues of operational and ecological efficiency of wheeled and tracked forest machines have been addressed within the framework of the direction, and previously a separate scientific specialty “Technology and machines of logging and forestry” for a long time now. This direction originated from the works of specialists in the field of agricultural mechanization, who studied the interrelationships in the “mover-soil-harvest” system in detail. Both in agricultural and logging production, when considering the interaction of forest machine movers with the driving surface, the methods of soil mechanics were and are widely used. However, forest soils are a much more complicated environment for theoretical and experimental study, as they have a pronounced layered structure, including organic and inorganic components, and, moreover, are penetrated by the root system of woody and shrubby vegetation. At present, wheeled forest machines of various traction classes dominate in logging production and forestry, which is due to their versatility, high operating speeds, the ability to move between harvesting areas on their own, including moving on public roads. Despite the considerable amount of theoretical and experimental research carried out by domestic and foreign scientists in the field of interaction of wheeled machines with forest soils, the issues of interrelation between the pitch of the ground hooks and the coupling of the mover with the soil have remained poorly worked out so far. This is due, first of all, to the fact that the evaluation of the machine’s passability by traction is given after evaluating the indicators of rutting and resistance to movement. This article is aimed at the theoretical solution of this issue, at the development of the approach to the theoretical assessment of the coefficient of adhesion of the wheeled mover of a forest machine with a soil.
