Abstract

The search for a solution to the problem of interaction of vehicles with the surface of the roadbed when driving on unpaved forest roads (agricultural roads or industrial transport communications) is quite relevant due to its insufficient theoretical knowledge. For this purpose, the issues of the functional purpose of an automobile engine, as a system of wheels with pneumatic tires, are considered.
The article contains an analysis of the design features of the rolling stock of forest vehicles, from the point of view of the combination of the axes of the rolling stock and the presence of wheels in them, which undoubtedly should be taken into account when transferring the rolling load through the contact spot with the ground surface. This aspect of interaction has a significant impact on the work of the road structure in the process of redistribution along its depth and width of the soil massif.
Considerable attention is paid in the article to the process of formation of ruts occurring in the thickness of the soil base when moving a movable wheel load along its surface. Theoretical studies indicate the dependence of the formation of ruts during the movement of wheels of running systems on the moisture regime of the soil, as well as their compacting effect on the soil base, which is directly related to the shape of the tires used and the nature of the pressure distribution in the contact patch.
