Interaction features of a forest vehicle propulsion when maneuvering on a cryolithozone slope under cyclic loads

Logging and forestry operations in forests on slopes on permafrost in the warm season cause increased stress on forest ecosystems.Mainly, they have an impact on soils.Normal and tangential stresses transmitted from a forest vehicle propulsion to the thawed layer of seasonal permafrost result in shear deformations that lead to formation of a track and compaction of the soil.In turn, these phenomena negatively affect the root systems of undergrowth and the trees left to grow and may cause erosion processes.The melting of the seasonal permafrost layer leads to an increase in the moisture content of the upper soil layer, and, consequently, a sharp decrease in its bearing capacity.As a result, the intensity of the track depth rate increases.To
