The purpose of the work is to increase the efficiency of the mechanical equipment of the road construction complex by improving the structures and energy saving. Both theoretical and experimental research methods were used in the work: field samples testing, theoretical description of work processes, modeling of operating loads, mathematical modeling of motor graders, bulldozers, scrapers, loaders. Methods of adaptation of earthmoving and transport machines to the conditions of external loading are developed. A physical model of the friction unit with particles of lubricant contaminants is developed The dynamic loads in the mechanism of lifting the load of the bridge crane are investigated. The measuring complex for research of loading of the running gear of the full-scale model of the tower crane is developed. The review and information technologies at designing and operation of BDM are executed. Equipment for on-board diagnostics of hydraulic drive of construction machines has been developed and improved The influence of support load distribution on the stability of tower cranes is theoretically investigated. Determining the zone of soil deformation during its pushing by the working body The analysis of conditions of formation of microcracks in the basis of microroughnesses at their repeated interaction is executed A study of the stability of the self-propelled scraper when working on the slope. A study of the stability of a small loader when moving a threshold obstacle. Simulation modeling of three-dimensional hydraulic drive of excavator equipment is carried out. The dynamics of the volumetric hydraulic drive of the crawler sidewall of the tractor TS-10 is investigated Determination of indicators of course stability by means of analytical model of movement of a motor grader is executed. A mathematical model of a short-base loader when moving over an obs Product Description popup.authors Efimenko Olexander V Ivanenko Oleg I Avrunin Grigory A Wenzel Eugene S Kovalevsky Sergey G Kosolapov Victor B Musaev Zaur Zaur R Orel Oleksandr V Pimonov Igor I Razaryonov Leonid V Suponev Vladimir M Fidrovska Natalia M Kholodov Anton P Chaplygina Oleksandra M Scherbak Oleg V Schukin Alexander V Yarizhko Olexander V popup.nrat_date 2020-10-01 Close
