Abstract:

In order to realize the estimation of tire mechanical characteristics and the identification of tire models that do not rely on the physical sample of tires， and to accelerate satisfying the technical and accuracy requirements of tire virtual delivery， in this paper， based on the finite element software ABAQUS， a method for simulating the tire camber-turn-slip combined condition is proposed， and the influence of camber on the turn-slip is analyzed. Firstly， the tire finite element model is constructed， and the simulation accuracy of the model is verified by the bench test data， and simulation methods of tire camber-turn-slip combined using implicit solver is proposed. Secondly， According to the spin turn condition under the special case of turn-slip， the influence of the inclination angle on the spin turn aligning moment is analyzed. Finally， the camber-turn-slip conditions of tires with different load are simulated， and the influence of camber on the lateral force， aligning moment stiffness region and the whole area of the turn-slip mechanical characteristics are analyzed. It is concluded that the camber has a significant nonlinearity on the stiffness area of the lateral force and aligning moment， and affect the curve features of the decay rate of the lateral force， the curvature of the transition zone of the aligning moment and so on.
