Abstract

The aspects of the negative impact of wheel movers when moving on unpaved bases with low loadbearing capacity are considered. It is shown that modern transport and technological machines equipped with such running systems are heavy-duty, large-sized cross-country vehicles that must ensure the efficient operation of production processes. The variants of interaction of various types of wheel schemes (single-pitched tires, paired wheels and wheels with low-profile tires) with a dirt surface are analyzed. This allowed us to conclude that the horizontal and vertical displacement of the soil in the area of the wheel contact spot is uneven, and also showed how the specific pressure is distributed over depth when exposed to multi-profile tires. The methods of reducing the magnitude of stresses arising in soil massifs are investigated. Their main advantages and disadvantages are given, which indicate the need for a comprehensive solution to the problem of interaction of wheel systems with ground surfaces. The assessment of the impact of forest wheel thrusters on the ground in places of joint contact made it possible to develop directions for increasing the efficiency of soil foundations and roads.
