Abstract: Under economic sanctions the development of heavy-duty mining dump trucks domestic production has become extremely important for ensuring Russia’s technological sovereignty and increasing the marketability of home-made machines. The article provides a comprehensive analysis of existing approaches to product development. Special attention is paid to the comparative analysis of two different design methods, i.e Russia’s system of development and production and the foreign approach, which includes the creation of the future product concept, its development and further production. The main advantage of the Russian system consists in a well-organized proven legal framework. The authors emphasize that it could be enhanced by the advantages of foreign methods, in particular by making it more flexible and adding deeper digital integration at all stages of product design. The authors did a research on load-bearing systems of mining dump trucks design to identify the level of consistency. The main result of the research is the development of a new methodology for designing the load-bearing systems of dump trucks, which combines the elements of Russian regulatory requirements and advanced foreign practices. The proposed methodology includes a complex analysis of product designing stages, with suspension types and operation conditions taken into account, as well as multibody system dynamics modeling and durability and fatigue life calculations. The authors identified several issues of dump trucks load-bearing systems design need resolving: lack of precise selection criteria for cross-sections of mechanism elements, normative stiffness figures and reliable methods of assessing welded joints fatigue life indicators. Those issues are stressed as promising for future research. The implementation of the proposed methodology might shorten the development time, reduce costs and increase the marketability of the domestically produced dump mining trucks. Practical relevance of the research lies in establishing a methodological basis for the development of competitive home-made dump mining trucks, which is particularly important due to the imposed sanctions and the need to develop Russia’s own mining industry machines.
