Study on Dynamic Roll Stability of Articulated Engineering Vehicle Based on Virtual Prototype

Most rollover accidents involve articulated engineering vehicle due to the center of gravity shift when steering. In this paper, a virtual prototype model of a loader as the typical articulated engineering vehicle is built using multi-body dynamics software. The dynamic simulation of steering characteristic under different slop and speed is made and the roll stability is analyzed. The stable working range of the loader obtained from the simulation results can give reference for the drivers selection of vehicle route and safe operation. This paper has a certain meaning for further study of articulated vehicles roll stability.
