Forestry vehicles meet different kinds of soil resistance when operating on forest soils, which include the rolling resistance, as well as the resistance to vehicles turning. The purpose of proposed study is to present dependencies for estimating the soils resistance to forestry vehicles? turning, based on solution of theoretical problem of indenter pressing into a soil massif of unlimited thickness of the deformable layer. The study bases on theoretical methods of terramechanics, methods of computational experime...

The study aims to estimate rut depths components caused by soil compaction and its? shearing caused by forestry vehicles? impact. The study bases on theoretical methods of terramechanics. As a result of the calculations, the study estimates three components of the rut depth caused by wheeled and bogie-tracked forestry vehicles impact. In the case when wheeled forestry vehicles operate on a weak forest soil which bearing capacity is up to 0.04 MPa, the estimate of the rut depth component caused by the soil shear ca...
