Tire Camber Turn-Slip Combined Simulation Using Implicit and Explicit Finite Element Analysis

ABSTRACT

The mechanical properties of tire turn-slip primarily reflect the mechanical characteristics of tires operating at low speeds with yaw angular velocity. Acquiring such tire force data is beneficial for improving the accuracy of tire model expressions under conditions of low speed and large turning angles. Currently, mainstream tire test benches lack the capability to test the pure turn-slip of tires. In exploring virtual sampling methods for tires, tire suppliers rely on predictive and virtual data for tire model identification. The acquisition of turn-slip data can expand the applicability of tire models. Furthermore, no researchers have publicly published results on estimating the mechanical properties of tire turn-slip by using finite element analysis. Thus, this paper proposes a tire camber-turn slip combined simulation method based on implicit and explicit finite element algorithms. First, using a non-pattern tire model, implicit and explicit simulation methods for camber turn-slip combined conditions are developed based on ABAQUS software. Second, the mechanical characteristics of tire turn-slip under different loads and inclination angles are analyzed and the distribution of tire forces in the contact patch is obtained using two simulation algorithms. And third, the reliability of the linear characteristics in the simulation results is evaluated and the influence of inclination angles on turn-slip characteristics under the two algorithms is compared. The results indicate that the bias of both algorithms shows consistent trends in the effects of camber, demonstrating high data reliability. Additionally, the mechanical characteristics of tire turn-slip obtained through finite element simulation effectively estimate its mechanical properties.
