“…Figure 5(b) represents a 3-D patterned tire model constructed by our in-house program with trilinear finite elements, in which the incompatible surface-to-surface tying is employed to assemble the fine tread mesh and the coarse body mesh. The reader may refer to our previous paper [4] for the details on its mesh generation procedure.…”

“…From a fluid dynamics point of view, the tire wet traction is characterized by the flow pattern of rainwater drained through the tire grooves [2,3], so that the detailed tread geometry should reflected into the tire modelling [4,5]. As well, another careful consideration must be paid to the calculation of the frictional heat loss at the disc pad because most of the vehicle kinetic energy dissipates at the disc pad.…”

SUMMARYA wet-road braking distance estimate for the vehicles equipped with ABS (anti-lock brake system) is presented in this paper. The entire speed interval at braking is divided into several uniform sub-intervals, and the energy conservation law is applied to individual sub-intervals to predict the intervalwise braking times and the resulting velocity profile at braking and the total braking distance. The proposed method is based on a numerical-analytical approach such that the frictional energy loss of the patterned tire is computed by 3-D hydroplaning analysis while the other at the disc pad is analytically derived. The operation of ABS is numerically implemented by controlling the tire angular velocity such that the preset tire slip ratio on the wet road is maintained. The tire hydroplaning is analysed by generally coupling an Eulerian finite volume method and an explicit Lagrangian finite element method. Illustrative numerical experiment is presented to support the validity of the proposed estimate.

“…It is established practice to model only the circumferential grooves in the tread in tyre finite element models, but recent research [6,22] indicates that including the detailed tread pattern significantly improves the accuracy of the footprint, contact pressure and lateral behaviour. A difference in the contact stress distribution was also detected [6,22]. Using only the circumferential grooves does however give almost identical results for lumped variables such as tyre deformation and dynamic radius [6].…”

This paper investigates the possibility of using a coarse finite element model with bulk material properties, to model the vertical force-displacement characteristics of a tyre, for the purpose of tyre model parameterization. The paper proves the approach on a light truck off-road tyre. The practical application is intended, however, for very large tyres where physical testing is not feasible.The paper indicates that it is feasible to obtain bulk material properties from tensile tests on specimens cut from different positions on a tyre and to use these test results to parameterize suitable non-linear anisotropic material models. The non-linear elements defined in the Neo-Hookean and Ogden models, as well as elements with differing linear orthogonal stiffnesses, are combined with each other to simulate the global material properties of the tread and sidewall of the tyre.The global behaviour of the finite element model is analysed by comparing experimental and simulation data on a flat surface as well as various lateral and longitudinal cleats. The results confirm that the finite element model can predict with acceptable accuracy the vertical force vs. displacement, as well as the sidewall deformation of the tyre under static loading conditions on a flat surface and also on various different cleats, by using equivalent (global) material properties.The approach is accurate enough to be used in the parameterization of various tyre models.

A Non_Pneumatic tire (NPT) has spoke to replace air of the pneumatic tires. A NPT appears to have advantages over the conventional pneumatic tire in terms of flat proof and maintenance free. And a NPT can also be used in the space environment since it uses no air for inflation. In this study, the static contact pressure of NPTs with auxetic honeycomb spokes is investigated as a function of vertical loading and is compared with that of a pneumatic tire. The finite element based numerical simulation of the local stress of an airless tire is carried out with ABAQUS for varying vertical force and honeycomb spokes geometries.
