Research on the Burst-tire Car of Direction Instability of Dynamic Model Based on Load Transfer

In the paper, by analyzing burst-tire car of the main factors, and simplified to a linear system, the establishment of two degrees of freedom burst-tire vehicle dynamic instability model. This paper research the rolling radius of the burst-tire wheel of the burst-tire after the impact of the direction instability, and then analyzes the changes in driving posture as a burst-tire caused by load transfer, and as a result of load transfer on the side of each wheel lateral force. Finally, build burst-tire car of the two-dimension direction instability dynamic model.
