Abstract
The article presents a method for obtaining computational and experimental dependencies that describe the increase in resistance during the curvilinear movement of a wheeled vehicle along a non-deformable, flat horizontal supporting surface on the speed and curvature of the trajectory. The set of parameters controlled during the experiment includes information about the force factors on the axis of the wheel propulsion device; in this regard, the work examines the main features of processing data obtained using strain gauge wheels. The main distinctive feature of the proposed approach to assessing the increase in resistance during curvilinear movement is the ability to take into account the design features of the rotation of a wheeled vehicle as a whole, for example, the discrepancy between the steering angles of the steering wheels and the geometry of the steering linkage (Ackermann geometry), etc. It should be noted that these features are difficult to take into account analytically in simplified mathematical models of vehicle dynamics, for example, used to solve problems of optimization of the laws of motion, which makes this research relevant.
