Finite Element Optimization Design of Bead Structure of 315/60R22.5 Truck and Bus Radial Tire
Based on Abaqus and Tyabas finite element analysis software,the bead structural optimization schemes were proposed,and the finite element models were established according to the actual damage pattern of 315/60R22.5 truck and bus radial tire.The schemes were optimized through the analysis of the strain energy density,Von Mises stress,and shear strain LE13 and LE23 in the end area of the reinforcement material.The results showed that the stress and strain distribution at the end of the reinforcing material of the preferred solution was significantly improved through the bead structure optimization.The bead endurance test results of the finished tire were consistent with the finite element analysis results,and the bead endurance performance of the preferred solution was better than that of the initial design solution,and the optimal solution prolonged the bead endurance test time by more than 70 h,which realized the purpose of improving the bead endurance and extending the tire service life.
