【Abstract】 A 3D nonlinear finite element analysis is performed on 12.00R20 radial tire.By applying design sensitivity analysis(DSA) technique,the sensitivities of strain energy density(SENER) to the mechanics performance parameters of different rubber materials in main failure regions of tire are calculated.Based on the results of DSA,an optimization on different rubber materials for tire is performed to enhance the fatigue life of tire.The results are verified by durability tests on trail-manufactured tires.更多还原
