Research on cornering stiffness based on FEM

Based on one type of PCR tire,it builds the finite element models of treaded tire to investigate on the cornering properties in ABAQUS. The tire analysis is divided into two steps: implicit analysis and explicit analysis. The implicit analysis consists of the mounting,inflating and vertical loading. Subsequently,the time history of lateral force at varied slip angles is performed in the explicit analysis and then the cornering stiffness is obtained. The simulation results are consistent with the experimental ones,which confirm the validity of the proposed method. At last,it takes the simulations and experiments on the belt structure,the cap ply structure and the hardness of bead filler,shows that above items affect the tire cornering stiffness.
