Method for calculating the track depth after successive wheel runs on deformable soil

Wheeled vehicles (tractors, cars, earth-moving machines, trailers, etc.) used in the municipal service are designed to work both on hard and on deformable soil surfaces. When driving on the ground, the power consumption required to ensure the movement of a wheeled vehicle increases sharply. Questions arise related to the cross-country performance of vehicles, their controllability, loads in the transmission. In this regard, it becomes necessary to consider various aspects of the movement of these vehicles on deformable soil, in particular, determining the depth of the track left by the vehicle. This paper presents a method for replacing a deformable wheel with a pneumatic tire with an equivalent wheel of a larger radius, and also considers a method for determining the equivalent radii of the wheels, which makes it possible to determine the track depth with successive passes of pneumatic tires on various deformable soils. The required radii of equivalent wheels can be found by the described method using the results of experiments. The results of calculations using the derived formulas are in good agreement with the experimental data, which indicate the practical applicability of the obtained dependences.
