The purpose of the work is to increase the efficiency of the mechanical equipment of the road construction complex due to the improvement of structures and energy saving. Both theoretical and experimental research methods were used in the work: testing of full-scale samples, theoretical description of work processes, modeling of active loads, mathematical modeling of the work of motor graders, bulldozers, scrapers, and loaders. The substantiation of the durability of the bridge crane mechanisms has been completed. The substantiation of the method of adaptation of the earthmoving machine to operating conditions has been carried out The influence of the angle of installation of the motor grader dump in the plan on its maximum effort was studied, taking into account the random process of the emergence of a difficult obstacle. The development of rational parameters of the articulated connection of the 30-50 kN tractor class has been completed. The stability of the tower crane was investigated using computer simulation. An analysis of diagnostic systems for hydraulic drives of construction and road vehicles was carried out. A study was conducted to determine compaction and pressure on the soil with an asymmetric cylindrical tip. An analysis of the force interaction of elements of the loader's working equipment was carried out. An improved method of calculating the main parameters of a small loader with an on-board turning system. An analysis of the modern possibilities of using hydraulic motor-wheels in the transmissions of high-speed tractors was carried out. The results of modeling the influence of temperature on the thickness of the layer of surface-active substances adsorbed on micro-irregularities are given Product Description popup.authors Yefymenko Andrii O.
