Abstract. Intensified production, an increased fleet of vehicles with internal combustion engines, as well as increased operational mass of transport and technological vehicles continuously aggravate the environmental situation in the world every year. (Research purpose) To identify the main impacts made by the transport and technological vehicles on the environment and the problems associated with their disposal, as well as with the disposal of automobile and tractor tires. (Materials and methods) The authors have generalized the materials published in periodicals, as well as the results of bench, field and operational tests of the transport and technological vehicles. (Results and discussion) The authors have identified the problem of the destructive impact of the wheeled movers on the supporting road surface, the soil and the soil cover. Measurements have been taken under the contact area of several mover types and the values of the stress-strained state of the soil affected by these movers have been determined in the form of the distribution of normal stress diagrams. The authors have also studied the influence of the design features of transport and technological vehicles performing curvilinear motion on the track size and soil destruction and identified characteristic patterns of the track. Conclusion has been made that in winter the level of environmental pollution depends on the road surface condition and the use of chemical reagents for deicing. The authors have considered a possibility of using electrical-and-hydraulic technology for the disposal of transport and technological vehicles and stressed the need to form regulatory documents for the designing, operation and disposal of transport and technological vehicles, taking into account foreign experience in organizing the environmental management system, as well as environmental auditing and labeling, the procedure for assessing the environmental performance of production systems and products at all life cycle stages. (Conclusions) The paper presents the main impact factors of the transport and technological vehicles on the environment during their life cycle up to full disposal. The authors have proved the need for a safe and energy-saving electro-hydraulic technology for the disposal of electronic components and batteries of transport and technological vehicles based on selective destruction of plastic casings and the separation of pure noble, rare-earth and other metals and their alloys.

“…In recent years, researchers have increasingly used various methods for modeling rolling resistance, traction and other indicators of tractors and machines [4][5][6]. Nevertheless, obtaining a tractor power balance in the field, using modern sensors and a new generation of recording equipment, allows a more objective assessment of the processes occurring in the machine-transmission-tire-soil system [7][8][9] It is well known that the power balance of any mobile power tool moving uniformly on a horizontal surface can be written as follows:…”

This article describes the methodology and results of the experimental determination of the stat-ic-elastic damping characteristics of the Sibeco air suspension with a scissor guide mechanism. To implement the measurement procedure in laboratory conditions, bench equipment, including a compressor unit (power system) with a control pressure gauge, a measuring device (height gauge) for fixing linear displacements and reference weights, was used. The measurements were carried out stepwise at various fixed values of air pressure in the pneumatic elastic element, as well as in the presence or absence of a standard unregulated hydraulic shock absorber in the design of the con-sidered seat suspension system. The whole process of obtaining the necessary parameters was held in accordance with the recommendations of the official domestic regulatory documentation, which establishes regulations on the general technical conditions for the design of seats for automotive ve-hicles. There were analyzed the obtained curves of the static characteristics of the seat suspension, including for the presence of a character of nonlinearity in different specific sections of the charac-teristic. Based on these results, the values of the parameters of stiffness, natural frequency and re-sistance forces (“dry friction” forces) were calculated during the compression and rebound strokes of the seat suspension for certain measurement conditions. Additionally, an assessment for the com-pliance of these parameters with the normative indicators of domestic technical standards was made. Also, the dependences of the instantaneous values of the stiffness of the considered air sus-pension of the Sibeco seat on deformation at various air pressures in the pneumatic elastic element were constructed and analyzed. Recommendations on the operation of this device for cushioning the seats of operators of motor and tractor equipment were given.
