Field studies of the profile passability of the experimental vehicle for cargo transportation in agriculture

Introduction. The transportation of goods in the field of agriculture plays an important role and is a link in all technological stages of the life cycle of agricultural products. The implementation of transport work in the agricultural industry is a complex technological process, which, due to adverse weather conditions and rugged terrain, is complicated and often leads to difficulty in the movement of trucks or even to their jamming. To expand the functionality of vehicles when moving on a supporting surface with a weak bearing capacity and rough terrain, an experimental vehicle was designed, which, depending on the operating conditions, has the technical possibility of a combined mode of movement – rolling and walking, providing it with advantages over vehicles, moving only by rolling, one of which is profile patency.

Object. The object of the study is the profile cross-country ability of the experimental vehicle.

Materials and methods. The profile cross-country ability of the experimental vehicle was determined in the field when studying the parameters - the largest angle of the slope to be overcome, the largest width of the ditch to be overcome, the maximum height (depth) of the obstacle to be overcome. The profile cross-country parameters were studied using original technical solutions incorporated in the design of the experimental vehicle, and without them.

Results and conclusions. The original technical solutions included in the design of the experimental vehicle, which allow moving in a combined way, made it possible to increase the angle of the slope to be overcome in the transverse direction by 2 times from 200 to 400, the width of the obstacle to be overcome from 0.84 D to 1.86 D, and the height of the obstacle to be overcome obstacles from 0.37 D to 0.65 D (D is the outer diameter of the mover). The results obtained expand the possibilities of using the experimental vehicle when working in areas with rugged terrain, along irrigation canals, areas located in close proximity to the roadbed, as well as when overcoming ditches, ditches and pits.
