“…It is obvious that the number of waves is smaller than in the previous case, Figure 6. The standing waves profile is similar to those observed in the experiments, [7], [23]. They attenuate significantly before reaching the leading edge of the contact region.…”

“…In addition, a diagram of the bearing reaction force, F, as a function of the tyre expansion due to the centrifugal load is shown in Figure 8. The diagram is very similar to the experimental one, [23]. In Figure 9, diagrams of both the ring expansion and the bearing reaction force as functions of the rotation speed are shown.…”

A new theory of contact-induced standing waves in rotating tyres is presented. The tyre is run by a rotating drum with a fixed shaft distance as in experiments. The tyre belt is modelled as a rotating ring whereas its sidewalls are modelled via radial stiffness of an elastic foundation supporting the ring. The differential equation of vibrations is reduced to the radial deflection of the ring. Critical rotation speed depends on the inflation pressure and the ring bending stiffness. Different tyre response functions are defined in the rotation speed domain with respect to the critical speed. The contact region between the tyre and the drum is defined considering the increase of the tyre radius due to the centrifugal load. Appropriate boundary conditions are specified in order to ensure a continuity of the ring deformation. Bearing reaction forces, as a result of drum penetration into the tyre, are defined.

“…The tire carcass colloid and the cord and other skeleton materials are formed by mutual bonding, which causes the turn-up point of the skeleton layer such as the ply to easily cause the rubber to open and separate. This results in tire bulging and plastic deformation [12]. By simulating the longitudinal sliding process of the tire, the force analysis of the fetal crown ply, 1# belt ply and 1# ply in the tire frame material is carried out.…”

Select 215/55 R17 radial tires for material test to obtain relevant material parameters. Use these parameters to build a finite element model and conduct longitudinal slip simulation. The relationship between longitudinal force and slip rate at different speeds and loads was determined by tire longitudinal slip tests. Then the longitudinal slip simulation results are compared with the test results to verify the feasibility of the model. The circumferential and axial Rebarforce of the belt layer at different speeds and the extreme value of the circumferential Rebarforce on the reverse-envelope of different skeleton materials are analyzed. The results show that: in the static state, the cord force of the belt layer will show a trend consistent with the direction of the cord arrangement. As the speed increases, the belt cord force exhibits significant fluctuations and asymmetry. The Rebarforce of the turn-up points on the belt and ply is significantly smaller compared to the fetal crown ply. The Rebarforce at the fetal crown and belt wrapping points at 60km/h is smaller than at 40km/h and 80km/h. The cord force of the fetal crown ply and the belt ply is much more affected by the load than that of the ply.

“…In such models, the tyre belt is typically modelled as a ring, whereas the tyre sidewalls are approximated by distributed radial stiffness. Nowadays, 3D FE models are ordinarily used for the verification of tyre designs, [14][15][16][17][18][19][20][21][22].…”

A physics-based mathematical model for the simulation of contact-induced standing waves in rotating tyres is presented. A toroidal balloon mounted on a hub, in contact with a rigid flywheel, is considered. The distance between the hub and the flywheel shafts is kept constant during rotation. The balloon is modelled as a membrane structure, i.e. as a ring on elastic support without flexural stiffness. The differential equations of motion for the ring radial and circumferential displacements are formulated according to the cylindrical shell theory. It is found that the critical rotation speed is a transition parameter from a stable to unstable state, whereas the standing waves denote ring post-buckling behaviour. Boundary conditions at the ring and flywheel contact edges are specified so as to ensure the continuity of ring deformation. The internal load due to the penetration of the flywheel into the expanded ring, as well as the reaction forces in shaft bearings, are determined. The influence of the circumferential displacement on ring response is also analysed. The analytical procedure is verified by comparing the numerical and the available experimental results. In spite of a rather simple balloon model, a good qualitative agreement between the two sets of results is obtained.
