Abstract: In the process of designing and validating vehicles the methods of mathematical multibody modeling are actively used at almost all stages to solve engineering problems. Modeling of multibody systems is used to study the behavior of complex systems consisting of a large number of connected and moving parts. Multibody models are developed in the image and likeness of the digital models preceding them, which have a typical software format of сomputer-aided design. The most characteristic tasks in automotive industry, which are solving with the help of multibody modeling tools, are the tasks of determining the loads on the power structure of vehicle. In the field of passenger cars, domestic and foreign researchers have significant developments on this area, however, there are still certain problems in determining the loads for the power structure of off-road heavy-duty vehicles. The general characteristic of the problems lies in the absence of a normative procedures which are instructing the effective use of multibody modeling tools in determining loads at the early stages of design. This article describes the results of the development of a procedure for de-termining the loads on the power structure of quarry dump trucks, as a special case of the off-road heavy-duty vehicle, and also describes the experience of using this technique on the example of modeling the loading of the front suspension of a quarry dump truck. The basics of the procedure are the features of the construction of mathematical models, the formalization of typical load cases and the method of modeling loading. The purpose of the work is to form prerequisites in the field of developing the normative procedures for building the effective process of designing the chassis of off-road heavy-duty vehicles.
