Tire rolling resistance has a significant influence on fuel consumption in cars and trucks CO2 emissions. Rolling depends the tire construction, pavement texture stiffness, as well environmental traffic conditions. This article presents pilot study impact of passenger car tires. Reasons why Mean Profile Depth is not good descriptor characteristics from point view are presented, an experimental ...

Gamma processes and their variants are natural choices for degradation modeling of many products. Motivated by practical needs, this paper investigates semiparametric inference of the simple gamma process model and the random effect variant. Maximum likelihood estimates (MLEs) are obtained through the EM algorithm, while the confidence intervals are constructed via the bootstrap method. The sim...

Abstract The employment of intelligent tires to test the vehicle performances is ever-increasing in last years. Many research activities have been made correlate measurements provided by sensors tire dynamics. In this paper, a novel tire-road forces estimation technique presented. developed estimator based on an approximation well-known Flexible Ring Tire Model (FRTM) and therefore, it suitable...

The most important task of the tire is to ensure driving safety by optimally transmitting required longitudinal and lateral forces. Although great progress has been made in past development new materials patterns, many questions remain unanswered field elastomer friction on rough surfaces. This particularly true when an additional intermediate medium introduced into contact, as for braking wet ...

afinite element model of a bias truck tire under static vertical load using a global/local technique is designed in two parts. in the first part a previously created model for radial tires is developed to take the constructional variables of bias tires into account. it is shown that the technique can successfully be used for bias tires. the main challenge here is the selection of the initial la...

Euler-Lagrange coupling method is used to establish the fluid-structure interaction model for tires with different tread patterns by obtaining grounding mark and normal contact force between tire road surface during rolling. The altering of load force, pressure, water film thickness in relation effect on tire-road both constant speed critical hydroplaning was analyzed. Results show that are pos...
