A 3D finite element model of modal analysis has been established based on MSC.MARC software according to the practical structure of 195/60R14 radial tire. The rebar model is employed to simulate complex multilayer rubber-cord composites. The model considers the geometric non-linearity and the non-linear boundary conditions from tire-rim contact and tire-road contact. The modal test systems are developed for the free suspension tire and the grounding tire. The vibration characteristics of the radial tire are studied numerically and experimentally. Mode shapes (lobes) of the radial vibration are in a strong regularity with the change of the mode order. The first mode shape has two lobes, the second mode shape has three lobes, and so on. Changes of the inflation pressure do not affect the mode shape, but the natural frequency of higher mode shape is sensitive to the change of the inflation pressure. The mode shapes of the grounding tire become asymmetric due to the effect of the vertical load, and the frequency of each mode has a mutation when the vertical load is larger than 3000 N. It is in good agreement between the FEA and experimental results of the free suspension tire.

The 3D finite element method modeling based on MSC.MARC software was studied and a non-linear FEM model was developed. The non-linear mechanical properties of elastomers were described by the Mooney—Rivlin model. The rebar model was employed to simulate complex multilayer rubber—cord composites and directly define the cord directions varying with their positions. The radial tire model was established based on consideration of the geometric non-linearity due to large deformation, the material’s non-linearities of cord—rubber composites, the non-linear boundary conditions from tire—rim contact and tire—road contact. The steady-rolling performance of 195/60R14 radial tire was analyzed numerically. Under free-rolling state, centrifugal force had a certain effect on the contact performance of the radial tire. Under load rating, the stiffness of tire increased with the increase of the rotary speed. Under braking state, high stress region moves to the direction contrary to the running direction. The high stress region moves to the running direction under driving state. Compared with braking condition, the level of normal stress and friction stress in the contact region was higher under the driving conditions. Cord equivalent stress of the tire belt was larger near the tire shoulder, and smaller in the center of contact zone. Cord equivalent stress increased sharply with the rotary speed. Meanwhile, the maximum cord equivalent stress was higher under the driving state. The gradient of strain energy density near the belt end was larger. The strain energy density of the tire shoulder was the largest.

“…In [22], Ghoreishy presented an axisymmetric 2D model of a tyre and a full 3D model. The 2D model is only suitable for inflation analysis, whereas the 3D model, which is generated by revolving the 2D elements about the symmetry axis, has been used for footprint and steady-state rolling analysis.…”

The next generation of tyre sensors will be bonded directly onto the inner liner (IL) in order to measure important parameters such as strain, vehicle load, contact pressure, the tyre-road friction coefficient or wear. Sensor packages (SP) have a sensor node, which is bonded and kept in position by a specifically designed rubber housing (RH). Since the measurements they provide to the car control unit are used to improve the active or passive safety of vehicles, these packages can be considered critical safety components that should be dimensioned carefully. A tyre analysis, whether statical or dynamical, in which the complete structure is considered, under any load, inflating pressure or temperature working condition is mainly oriented towards defining the tyre product. The insertion of an SP inside such a complex tyre model, with the purpose of only analysing its behaviour, would be too time consuming considering the strong nonlinear behaviour of the tyre model. Therefore, this work presents a method that can be used to define a computationally lightweight finite element method (FEM) simulation, which is able to recreate the working conditions to which an SP is subjected. The basic idea behind this method is to separate the analysis of the SP from the structural tyre analyses; the latter is only run once, independently. The first task is to impose the deformed shape on a simplified model of the tyre with a bonded SP. All the deformation states that occur during rolling are computed in a static FEM simulation. The second task is to apply the inertial forces that act on the SP, whether computed or measured directly on the tyre, as external loads. These tasks are implemented in user-defined routines that are executed by the FEM solver. The method permits the stress concentration inside the RH material volume to be identified, at any angular position of the wheel. This information is then used, during the design process, to identify the most suitable geometry to level out the stress distribution. The resulting shape can be tested under different boundary conditions, by substituting the corresponding data arrays, but using the same FEM model. Since the deformed shapes and inertial forces are stored as simple text matrices (which are also used to form a test library), they can be easily interchanged in a flexible way. This more extended design process can reduce the costs of prototyping moulds. The proposed methodology has been developed and tested for the Pirelli Cyber TM Tyre project.
