Puncture vehicle of direction instability dynamic modeling and simulation

Currently, puncture vehicle of dynamic model is very few. In this paper, by analyzing puncture vehicle of the main factors, and simplified to a linear system, the establishment of two degrees of freedom puncture vehicle dynamic instability model. This paper research the rolling radius of the burst-tyre wheel impact the vehicle´s direction of instability, and then analyzes the changes in vehicle attitude as a puncture caused by load transfer, And the characteristics of the load transfer caused by the combination of tires on each wheel cornering force of the size of the vehicle traveling direction of the impact of instability, in which Magic Formula tyre model is applied to establish the formula lateral angle and lateral force of the correspondence. Finally, build puncture vehicle of the two-dimension Vehicle dynamics model.
