Tire-Pavement Coupling Dynamic Simulation under Tire High-Speed-Rolling Condition

Abstract

The coupling effect between tire and pavement is an intensively researched subject to analyse the dynamic interaction of the vehicle-pavement system. By considering the 11.00 R20 tire and expressway asphalt pavement, ABAQUS software was employed in this study to establish an improved model for simulating the coupling effect, in which the tire rubber was taken as a neoHookean material and the pavement was taken as a multilayer structure. The coupling was achieved by considering the equilibrium equation and continuity conditions of the contact surface. The tire rolling, which was modelled by the "steady-state transport" method provided by ABAQUS software, was imported to the tire-pavement coupling for the explicit dynamic computation. Numerical results indicate that the pavement deformation obviously weakens the tire vibration in comparison with the non-deformable assumption, in which the variance of the vertical acceleration at the tire centre is reduced by 25 % and the power spectral density is decreased by 52 %. The influence of the horizontal contact stress (CSHEAR) is considered by taking different friction coefficients. Compared with the case without the CSHEAR, the stresses in the longitudinal and lateral directions within the contact area on the pavement surface are increased by approximately 45 %. This study simulates a more realistic situation, including the contact stress and high-speed-rolling tire, thus the conclusions provide a reference for the optimization and design of vehicles and pavement structures.

Finite Element Analysis for Rutting Prediction of Asphalt Concrete Pavement under Moving Wheel Load

“…To further improve computing efficiency, they transformed the dynamic wheel load into a static-accumulated load. For the transverse section of pavement, the actual wheel load used is pulse load, and the staticaccumulated load could not accurately reflect this feature of the wheel load [7].…”

Influence of Operating Conditions on a Cast-Iron Manhole Cover

“…The geometric model was simplified into three layers with homogeneous isotropic material properties: tread and side rubber, reinforcement belts under the tread, and side carcass reinforcements. The material properties of the rubber matrix in the carcass and belt inserts were modelled on the basis of data from the study of Wang et al [21]. They are listed in Tables 1 and 2.…”

Review of Research on Tire–Pavement Contact Behavior

“…Although various tire-pavement contact models are available to analyze tire-pavement contact behavior and even the influence of pavement surface properties on the contact behavior, these models all assume the geometry and height distribution of a micro-convex body while ignoring the interaction between different contact zones; therefore, the usability of these models is very limited. With the development of computer technology, some researchers have begun to simulate tire-pavement contact behavior on computers and calculate tire-pavement contact stresses and contact areas via numerical simulation [14,60,97]. The modeling process is shown in Figure 13; contact behavior analysis is carried out by constructing models of tires and road surfaces, and some models even consider the water factor and can carry out water-wading calculations.…”
