Finite Element Simulation Analysis of Influence of Tread Compound Formula of Steel-belted Radial Tire on Tire Stiffness Characteristics
Taking 245/45R18 steel-belted radial tire as the research object,a finite element model was established,and an orthogonal experimental design was carried out on the tire tread compound formula to study the effects of different formulas on the radial stiffness,lateral stiffness,longitudinal stiffness and torsional stiffness of the tire.The results showed that the tread compound formula had the greatest impact on the torsional stiffness of the tire,followed by longitudinal stiffness and lateral stiffness,and had almost no effect on radial stiffness.The dosage of carbon black N234,silica 7000GR and the environmentally friendly aromatic oil were the main factors affecting tire stiffness.The tire stiffness increased with the increase in the dosage of carbon black N234 and silica 7000GR,and decreased with the increase in the dosage of the environmentally friendly aromatic oil.The interaction between carbon black N234 and silica 7000GR was weakened,and the interactions between carbon black N234 and the environmentally friendly aromatic oil,and silica 7000GR and the environmentally friendly aromatic oil were enhanced.
