Abstract: In the absence of high-tech production and a constant increase in imports of quarry dump trucks, there is a need to develop scientific foundations for the creation of autonomous quarry dump trucks for open-pit mining. The article analyzes the composition of an automotive dump truck and highlights the main objects of research: cargo platform (body); load-bearing system (frame); front axle beam; drive axle beam (crankcase). It is revealed that there is a need to create or develop the production of components and materials in the Russian Federation for the AKS, such as the engine and its systems, wheels and tires, as well as components of the autonomous control system, hydraulic and low-voltage electrical equipment. The life cycle and tools for creating a digital twin of an autonomous mining dump truck, as well as methods for obtaining loads acting on research objects and other elements of a dump truck, are examined. A methodology has been developed for the digital creation of quarry dump trucks, providing the best technical and economic indicators, which is based on the use of digital technologies for modeling quarry dump trucks. Concrete examples show the results of the methodology of digital creation of quarry dump trucks. The scientific and practical results of the work are presented.
