“…Inflation of the tyre by a uniform internal pressure. In accordance with widely accepted modelling methodology [2,3], the inflation pressure is assumed to stay constant during the vertical loading simulation and hence is treated as providing a distributed load acting on the inside surface of the tyre, see Figure 2.…”

“…To replicate the interaction between the tyre and the rim more realistically, the FE model of the wheel is made in two halves [2,3]. By this device, the mounting of the tyre on the rim can be simulated by moving each rim half from the outside towards the centre-plane of the tyre.…”

“…The tangential contact behaviour is simulated with a Coulomb friction model using a constant friction coefficient, denoted by µ. For the rim-tyre boundary the friction coefficient is set to 0.5 which corresponds to values found in the literature [2]. The friction coefficient between the road and the tyre is varied for the different simulations as outlined below.…”

Investigation of the stationary load-deflection behaviour of tyres reveals many details of the structure and the rubber to road friction properties. These characteristics are fundamental to the understanding of the behaviour of both the stationary and the rolling tyre. In connection with racing, tyre static stiffness characteristics are of interest as they reflect on the controllability of the vehicle to which they are fitted.In this paper, the construction of a finite element model capable of predicting the static tyre behaviour in great detail is presented. The model is validated against extensive experimental data, including contact pressure distributions and load-deflection characteristics. Static loading tests which involve variations in wheel camber angle and in the friction rules coupling tread rubber with the ground surface, are simulated with the tyre model. The results of the simulations reveal that a friction coefficient of 0.5 is sufficient to prevent sliding in static loading tests for this particular tyre. Lower levels of friction lead to tread sliding and reduced vertical tyre stiffness.Sliding is primarily lateral, leading to narrowing of the contact patch of the tyre. Narrowing also increases the local sidewall curvature which is part of the softening mechanism for both upright and cambered tyres. IntroductionTyre behaviour on a running car depends on carcass stiffness and rubber to road friction properties with complex interactions between them. In general terms, the small-effort behaviour primarily involves adhesion between tread rubber and ground surface and is dominated by carcass stiffness attributes, while the large-effort or near-limit behaviour has sliding of rubber relative to ground at its core. In the latter case, the behaviour is ruled by rubber to road friction forces. In racing, the main concern is with limit-behaviour but nevertheless, the small-effort demeanour is of interest, since it reflects on the controllability of the concerned vehicle.Many structural details of a tyre can be revealed by static load-deflection testing, in which the non-spinning tyre is loaded against a flat surface and detailed observations of deformations and stresses are made. If this kind of test is done in reality, many of the measurements needed are intricate and difficult but if the testing is virtual, no such difficulties arise. They are replaced by the need to develop a virtual tyre, the results from which can be taken to represent the real item.

“…Consequently, finite element modeling of tires has already become an essential procedure for the tire designer and researcher to improve the performance of tires. 2 Numerous investigators have performed simulations 3–7 and experiments 8–13 on the contact pressure distribution in the tire footprint region. Moreover, some optimization studies 14,15 on tire profile and patterns have been conducted to make the contact pressure uniform in the footprint area and to improve the wear performance of the tire.…”

A three-dimensional nonlinear finite element tire model with detailed tread pattern and a smooth tread tire model for comparison are constructed. The tire–rim and tire–road interactions are considered in these tire models. The static vertical loading and rolling procedures of the tire are simulated by using the ABAQUS code. Presented in this paper are the relationship between vertical loading and tire deflection, and the contact footprints, along with the pressure distribution achieved by the pressure-sensing pad experiment and the finite element tire modeling. The predicted results via the modeling method proposed in this study are in good agreement with experiments. In addition, the forces of belts, the deformation and strain energy density of tread blocks obtained from the tire model are also presented when the tire is in braking and traction rolling situations. The reliability of the proposed tire modeling methodology is validated.

Furthermore, some optimization studies on tire profile are performed in order to reduce the peak value of pressure distribution in the footprint.…”

Based on taking comprehensively into account the actual structure of the radial truck tire, including the contact non-linearity boundaries, such as tire-rim and tire-road interactions, an axisymmetric model and a three-dimensional nonlinear finite element tire model having four circumferential ribs are constructed in this investigation. With the aid of ABAQUS finite element analysis code, the static vertical loading procedure of the tire is simulated. The relationship between vertical load and vertical deflection, the contact patches with pressure distribution obtained by pressure-sensing pad experiment and finite element modeling are exhibited in this paper. It is shown that the results predicted by simulation are in good agreement with those of experiment. Moreover, the forces of belts and carcass obtained from finite element model are also presented when the tire is subjected to vertical load and contacted with rigid road. The reliability of the proposed finite element tire model and analysis methodology is verified.
