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.
Highlights
In the study of the trajectory and offtracking of the vehicle can be used various methods of field tests [4, 5, 7]
In source [28], the experimental procedure involves the installation of two nozzles on a road train, which spray paint at pressure and, as a result of processing individual points, get a trajectory of movement
To assess the compliance of similar models of the movement of road trains in computeraided road design systems, we decided to conduct an experimental study to determine the dynamic dimensions of road trains in real road conditions
Summary
In the study of the trajectory and offtracking of the vehicle can be used various methods of field tests [4, 5, 7]. In source [28], the experimental procedure involves the installation of two nozzles on a road train, which spray paint at pressure and, as a result of processing individual points, get a trajectory of movement. To study the trajectory of the movement of vehicles on the curves of different radii was applied the method of video [2, 6, 12, 27]. Prior to the use of computer-aided design systems, practically the only way to determine the minimum radius of congresses was special transparent templates depicting the dynamic dimensions of road trains at various radii of motion [26]. According to authors [11, 20, 23, 25], these methods are modern and more accurate to determine the off tracking of vehicles
