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 presents a methodology for determining loads, which allows at the modeling stage to determine the loads acting during loading and unloading of the cargo platform (body) of a quarry dump truck, as well as to evaluate the layout and design solution of the cargo platform (body) of a quarry dump truck. Two computational cases of modeling in the environment of dynamics of discrete bodies under the same conditions of the BELAZ 7513 cargo platform (body) and the developed cargo platform (body) within the framework of Government Decree No. 218 are considered. The process of loading and unloading of the cargo platform (body) of a quarry dump truck is modeled taking into account operation in real conditions. Concrete examples show the results of the methodology for creating quarry dump trucks. The scientific and practical results of the work are presented.
