The purpose of the work is to increase the efficiency of mechanical equipment of the road construction complex by improving structures and energy saving. The work used both theoretical and experimental research methods: testing of full-scale samples, theoretical description of work processes, modeling of active loads, mathematical modeling of the operation of the ZTM. The influence of initial deviations of the geometry of the cable drum shell on its stability was studied. The dynamics of the earthmoving and transport machine were studied taking into account the variable moving mass. X-ray, metallographic, and micro-X-ray spectral studies of the material of the bulldozer blades were performed in order to increase their wear resistance Computer modeling of the loading of the frame of an articulated tractor of the class 30-50 kN was carried out. The regularities of soil puncture by a cylindrical working body with an asymmetric tip in the form of an inclined flat front surface were studied A study of the loading of the working equipment of a small-sized loader was performed A calculation of the dynamics of the transmission of a loader with a hydraulic motor-wheels was performed Product Description popup.authors Avrunin Hryhorii A.
