Study on the influence of different tire cord structures on tire grounding characteristics

Abstract

The influence of different tire skeleton structural parameters on tire grounding characteristics was investigated. Using a 225/60R18 100H radial tire as the research object, the experiment and simulation were carried out by changing the diameter of the belt steel wire, the angle of the belt layer, and the number of carcass plies. Using the model parameters obtained from the rubber physical test, the finite element model of the tire was created in Abaqus for static loading simulations, the relevant data such as tire pattern impression and sinkage were analyzed, and the validity of the model was investigated. The influence of skeleton material on tire structure was deduced by determining the amount of stored strain energy of tire. The results showed that the belt angle in the grounding area had the greatest influence on the belt stress and presented a second-order change. However, the number of carcass cord layers and the diameter of the belt steel wire had little effect on the corresponding skeleton stress. The number of carcass layers had the greatest influence on the stored strain energy of the tires. The diameter of the bundled steel wire and the angle of the bundle had little influence.
