Abstract

The problem of cross-country ability of off-road vehicles and agricultural machines does not require its relevance at the present time. Moreover, an increase in the productivity and energy saturation of forestry and agricultural production machines leads to an increase in their mass, and, consequently, exacerbates the problem. Thus, the issue of taking into account the passability of forest machine materials is solved both by strengthening the road surface (increasing the number of layers of the road surface, the need for underlying ones, etc.), and by improving the movers.

The article discusses the most acceptable, effective and relatively easily accessible ways to increase the cross-country ability of vehicles equipped with oversized tires. Among the most commonly used solutions to the problem of increasing the cross-country ability and energy-saving qualities of wheeled vehicles is doubling the wheels, which leads to a deterioration in the turnover of the vehicle. Or the use of large-sized arched tires and pneumatic rollers, which increases the cost of the structure. The most effective way to increase flotation is to adjust the air pressure in the tires depending on the operating conditions.

The results of experimental studies of the stress-strain state of the soil massif are given for various values of the load on the wheel, the properties of the supporting surface and the values of air pressure in the tire. Specific recommendations have been developed regarding the optimal values of air pressure in the tires of the wheels, depending on the operating conditions, which in the general case allows to reduce the concentration of the track by an average of 15–20%, depending on the mechanical properties of the soil.
