Abstract: In this paper the authors of the article touch upon the issues of development of a methodology for determining the main geometric parameters of the hydraulic steering system of a dump truck on the basis of rational choice of the value of the maximum moment of resistance. This value is the basis of the process of parameterisation of the steering system of a dump truck. The wrongly accepted design value can affect the functionality of the dump truck in turning modes. At insufficient value of the torque most probably the designed dump truck will be unable to turn in a number of modes at operation, and strongly excessive value of the torque will lead to oversized units and increase of mass. Methods of mathematical modelling and known empirical formulas for determining the torque do not give unambiguous confidence results, because they require experimental verification. The formulae for calculating the moment of resistance to turning have been analysed. As a result of the work the methodology of determination of the basic geometrical parameters of the hydraulic steering system of a quarry dump truck is developed, which can be applied at the initial stages of design. It is noted that the choice of the formula for determining the maximum moment of resistance to turning is of particular importance in the developed methodology. The researches have shown that one of three formulas, named by famous scientists: B.N. Belousov's formula, M.I. Lysov's formula and A.A. Yenaev's formula, can be used for calculating the moment of resistance for dump trucks with a large positive shoulder of running-in. Further experimental works on determination of the moment of resistance to turning are planned on dump trucks with different types of suspensions. The development of the methodology is aimed at the development of recommendations for the construction of a dynamic model of steering control taking into account the hydraulic model of hydraulic cylinder control for loading modelling tasks
