Study of Cornering Maneuvers of a Pneumatic Tire on Asphalt Pavement Surfaces Using the Finite Element Method

Abstract

Field experience shows that most road accidents that occur during turning maneuvers are caused by the loss of vehicle control. The loss of vehicle control is often related to a lack of sufficient friction between the tire and the pavement surface. In experiments and analytical studies, the overall antiskidding performance of a pneumatic tire has been observed to be affected by operating conditions, road texture, and surrounding temperatures. Interactions of these parameters create a complex relationship between their combined effect and the tire's ability to combat skidding. One way to analyze the cornering maneuvers of a vehicle is by means of a validated finite element tool that can carry both the tire and the pavement properties. Few computational studies have been conducted to study the cornering performance of a rolling pneumatic tire, and none of these studies included the role of pavement surface morphologies in their analysis. In this study, a thermomechanical framework was used to analyze the influence of temperature on cornering friction. The cornering friction coefficient was found to decrease with an increase in the loads and the speeds. The cornering friction coefficient was found to increase with an increase in inflation pressure, sideslip angle, and pavement surface texture depth. The proposed study contributes to an understanding of the cornering performance of passenger car tires.

Study of Influence of Operating Parameters on Braking Distance

“…The braking distances are calculated from the friction measurements. It should be noted that readers can refer to the authors' previous works (14,15) for details on this validation process.…”

“…To validate the ability of the model to predict the friction coefficient, data measured by a French friction testing device called Adhera were used (24). The field experiments were performed on the French Institute of Science and Technology for Transport, Development and Networks test tracks at various speeds.…”

Effect of stone-on-stone contact on porous asphalt mixes: micromechanical analysis

“…Most of these studies used the computational technique based on the finite element method (FEM)/discrete element method (DEM). Although FEM/DEM based models are able to handle the detailed characteristics of various phases, they require largescale and sometimes impractical computational facilities (Anupam et al 2014, Anupam et al 2016, Anupam et al 2017.…”

3-D Thermomechanical Tire–Pavement Interaction Model for Evaluation of Pavement Skid Resistance

“…Recently, researchers used a staggered thermomechanical FE model to investigate the effect of temperature on skid resistance (21)(22)(23)(24)(25)(26)(27). These simulations were carried out using powerful parallel computation facilities.…”
