From a traffic safety point-of-view, there is an urgent need for intelligent tires as a warning system for road conditions, for optimized braking control on poor road surfaces and as a tire fault detection system. Intelligent tires, equipped with sensors for monitoring applied strain, are effective in improving reliability and control systems such as anti-lock braking systems (ABSs). In previous studies, we developed a direct tire deformation or strain measurement system with sufficiently low stiffness and high elongation for practical use, and a wireless communication system between tires and vehicle that operates without a battery. The present study investigates the application of strain data for an optimized braking control and road condition warning system. The relationships between strain sensor outputs and tire mechanical parameters, including braking torque, effective radius and contact patch length, are calculated using finite element analysis. Finally, we suggested the possibility of optimized braking control and road condition warning systems. Optimized braking control can be achieved by keeping the slip ratio constant. The road condition warning would be actuated if the recorded friction coefficient at a certain slip ratio is lower than a 'safe' reference value.

“…Three-dimensional tyre modelling based on overlaying the elements characterizing the cord on those made of pure incompressible rubber is described in reference [12].

The paper presents a full three-dimensional finite element model of pneumatic tyre. The inclusion of a special node to the model enabled to analyse the problem of static tyre-road contact under vertical, lateral or longitudinal external forces. The hyperelastic properties of rubber are described with the use of the elastic strain energy density function in the form of the third degree polynomial. Incompressibility is taken into account by means of the Lagrange multiplier-in the form of mean hydrostatic pressure determined within each finite element. Particular attention was paid to the directional properties of cord ply treated as monotropic linear-elastic material characterized by effective material constants. These properties were introduced into the model by overlaying the elements with monotropic material on those representing rubber. The total Lagrangian description with the Green-Lagrange strain tensor and the energetically conjugate to it the second Piola-Kirchhoff stress tensor were applied to the tyre model. The results of a truck tyre analysis concerning displacements and delamination stresses distribution show good accuracy of the pneumatic tyre modelling technique proposed in the paper.

“…Also, other researchers have carried out tyre modelling and studied tyre blow-out using the FE method and some results have been achieved. [7][8][9][10][11] Additionally, the tyre models that take into account the major components of a tyre, including the tread, sidewall, steel, etc., and the cord stress in the belt have been developed by numerical methodology. The model was validated by laboratory and virtual testing and can be used for crash and impact simulations including impacting a curb, driving over rocks, etc., for car, tractors and motorcycles.…”

The methodology for studying a tyre blow-out process using both experiments and simulations is presented in this paper. To achieve this, a tyre blow-out generator and an experimental device for tyre blow-out are developed. Moreover, tyre blow-out experiments in the static state are implemented. Then, the finite element tyre model corresponding to the experiments is established. The experimental results show that the tyre blow-out generator developed can effectively replicate the sudden inflation pressure loss without inflicting permanent damage on the tyre structure. The comparison between the simulations and the experiments shows that the finite element tyre model developed can simulate the tyre blow-out phenomenon and that the simulation analysis method is correct and effective. The tyre blowout generator developed and the finite element tyre model established therefore provide the basis for further simulations and investigations of tyre blow-out during the normal motion of a vehicle and its effect on the handling stability.
