Testing trajectory of road trains with program complexes

Abstract

The article provides information about using software for determination off tracking and trajectory movement of trucks. It describes experiment of determination of trajectory movement of trucks, using GPS system, to assess the compliance of similar models of the movement of road trains in computer-aided road design systems. Experimental study was conducted using truck KAMAZ 54115 and semi-trailer M 9397 in real road conditions. There are presented and compared results of the study of movement trajectories of road trains with results obtained of the Auto TURN software package application. Discrepancy between the curves is explained. As the difference in AutoTURN data in comparison with experimental values does not exceed 4.07 %, which, given the very similar nature of the curves, can be considered valid. As a conclusion the use of AutoTURN software package is validated for determining dynamic dimension of cars and for modelling trajectory of movement, not only for road trains, but also for all types of vehicles in the area of their design.
