Non-natural equilibrium contour design for radial tire and its influence on tire performance

Abstract

Two types of radial tire 11.00R20 and 385/65R22.5 are chosen as the research objects, and their carcass contours are redesigned by using Sakai Hideo's, Frank's and the new non-natural equilibrium contour design theories, which were based on analyzing the current non-equilibrium contour design theories of radial tire. Then the tire wear, rolling resistance and grip performance of the two radial tires designed by different non-natural equilibrium contour design theories are comprehensively analyzed with the finite element software ABAQUS. The results show that Frank's contour design theory can reduce tire wear; the new non-natural equilibrium contour design theory can enhance tire wear, rolling resistance performance, etc. It is also found that the tire carcass contour has great influence on tire performance, especially on the tire rolling resistance. The new non-natural equilibrium contour theory provides a guidance to reduce the tire rolling resistance, and it can break through the target conflicts in tire performance. The tire with the new non-natural equilibrium carcass contour can enhance its comprehensive performance.

Vehicle Dynamics, Lateral Forces, Roll Angle, Tire Wear and Road Profile States Estimation - A Review

“…From the microscopic point of view, [50] carried out a theoretical study from the rubber wear mechanism aspect on tire wear issue. Researchers in [51,52] utilized the finite element method (FEM) for tire wear estimation. While Tembleque et al [53] conducted the issue of tire wear and tire rolling resistance using the boundary element method (BEM).…”

A Strain-Based Method to Estimate Longitudinal Force for Intelligent Tires by Using a Physics-Based Model

“…Because the finite-element tire model established in this study was used only to identify the model parameters and verify the tire estimation algorithm, the model was constructed only considering the longitudinal pattern of the tire. The details of the tire model method were detailed previously in [26] and [27]. To improve the calculation accuracy of the contact area, the grid of the contact area was refined.…”

Investigation of rubber flow during tire shaping process by experiment and numerical simulations

“…Tire performance and its contact relationship with the road have a significant influence on vehicle performance, including the braking force, handling, and comfort. [1][2][3][4][5] Tires are supposed to fulfill the following functions: support vehicle weight, absorb forces, provide vibration damping, cushion the vehicle over surface irregularities, contribute to cornering stability providing adequate steering control, provide sufficient traction for driving, and braking in different surfaces, grant operational safety. [6][7][8] To fulfill these functions properly, tires are required to have some characteristics such as having low rolling resistance, rolling noise reduction, present excellent adhesion on wet surfaces, minimally heat up.…”
