Abstract:

Based on studies of car behaviour and stability, it has been determined that transversal stability should be considered as a multifactor one that means that among forceful and kinematic factors influencing the system “car-driver-road”, we should select those main ones, which have a significant impact on transversal stability. To this end, we have determined the dependences of car side slip and lateral movement on the movement speed and wheel-to-road adhesion coefficientduring the movement of car in running-away and brake-applied mode on turn. There is developed the assessment method for the impact of dynamic characteristics of tire and suspension bracket on car transversal stability.
