Studying the wheel slip when turning a car

The separation and lateral slip of wheels in the curvilinear motion of a two-axle vehicle can cause a loss of stability and controllability. In this paper, a three-dimensional model of a wheeled vehicle with a sprung mass represented in the form of a rigid body is used to study the influence of the vehicle sideslip on its handling and stability taking into account inertia effects. According to this concept, sideslips of individual wheels are determined and analyzed at various speeds of the vehicle in its curvilinear motion along a circular path. A three-dimensional mathematical model of a four-wheeled car is developed. A comparison of the calculated value of the critical speed of a turning car with its normalized value proved the validity of the proposed mathematical model.
