Verification of the Mathematical Model of Curvilinear Motion of a Semi-Trailer Truck

The widespread use of semi-trailer trucks in the transportation system is due to a number of advantages that can significantly improve the economic performance of transportation. To improve the efficiency, quality and safety of operation of semi-trailer trucks it is necessary to improve their properties. Mathematical modeling is one of the most promising methods for evaluating design solutions and testing the operation of automatic control systems aimed at improving performance properties of semi-trailers. However, the mathematical model being an approximate description of the simulation object expressed by means of mathematical symbols requires validation. In this regard, the developed mathematical model of curvilinear motion of the semi-trailer truck was validated by comparing the results of field and numerical experiments. The developed mathematical model has been proved adequate, and the possibility of using it for modeling curvilinear motion of semi-trailers to evaluate their operational properties has been confirmed.
