This study is based on the Tire and Rim Association (TRA) load formula, which introduced the relationship between static load and sinking force of the tire. It also established the mathematical model of the cord tension of any layer of the tire ring beam. A finite element model for a 195/65 R15 radial tire is established with the nonlinear analysis software ABAQUS, based on the tire structure and cord parameters. The calculated value from the TRA formula, simulated value and the experimental result demonstrates high consistency for the value of load sinking. Finite element simulation and experimental results of the load-versus-inflatable-section-width relation were compared, yielding little difference between the results. A similar analysis studies the change in the wavelength of sidewall standing waves at different vehicle velocities during high-speed tire-rolling. The value from simulation and the experimental results demonstrate high consistency, concluding that the wavelength of sidewall standing waves increases with vehicle velocity during high-speed tire-rolling. Thus, the accuracy of the finite element model is verified under both static and dynamic conditions. Based on the finite element model of the impact of change on velocity, load and tire pressure on tire cord stress, it can be concluded that with the increase in the speed and the tire pressure, the stress developed on cord increases and the impact of the load on it is lighter. Establishing the relationship between standing wave phenomenon and tire structural stress, it provides a certain mechanical basis for tire designers.

“…There are very few studies reported in the literature which have been concentrated on the prediction of relaxation length using the finite element (FE) method although the FE method is now routinely used for various aspects of tyre static and dynamic analysis. Finite element analysis has the advantage of facilitating the investigation of the effect of tyre material and structural properties on tyre behaviour and is widely used by automotive engineers and tyre designers [7][8][9][10]. Some typical examples are: Yang et al [11,12] who investigated tyre durability properties based on the variations in carcass ply turn-up and bead reinforcement turn-up using FE method; Behroozi and Olatunbosun [13] who conducted a study on the influence of FE model complexity on aircraft tyre performance characteristics; Mohsenimanesh et al [14] who developed a nonlinear and multi-laminated tractor tyre model to investigate the pressure distribution of an off-road tyre; Guo et al [15] who developed a detailed aircraft finite element tyre model for dynamic simulations of tyre loading upon aircraft landing scenarios using rubber and fabric material properties which were characterized and correlated.…”

This study investigates the influence of tyre structural layup and material properties on the relaxation length of a rolling tyre using finite element analysis. Relaxation length for rolling tyre under different operating conditions has been studied recently. However, the effects of tyre structural layup and material properties on relaxation length were ignored. In this present work, a finite element (FE) tyre model was built based on the material and geometry properties obtained from measurements of the tyre provided by a vehicle company. Rather than the common method (steady state rolling analysis) used for cornering behaviour simulations, ABAQUS/Explicit program was used for prediction of the cornering performance and relaxation length for a constant slip angle of the rolling tyre. Two different steer inputs were applied to the rolling tyre in terms of slip angle variation, namely step input and ramp input. The effects of various factors, including cross-section area, spacing, crown angle and strength of the tyre reinforcement cords, on relaxation length of the rolling tyre were investigated by numerical experiments using the design of experiment (DOE) method.
