Evaluating the tire wear quantity and differences based on vehicle and road coupling method

Abstract

Tire wear quantity and difference is one of the main points that affect the intension of tire road print feature and is under a tight link not only with tire road friction energy but also with vehicle dynamics. The proposed methodology aims to provide a mathematical method to analyze tire marks' feature for prediction the vehicle operating status in pro-and post-crash phases. The kinetic sliding friction coefficient considering the road effect is simplified with the new real contact area model. After, a simplified 9 degrees of freedom vehicle dynamics model by coupling the tire dynamic model is set up, and the effectiveness of the model is evaluated with vehicle stability measurement equipment. Furthermore, a theoretical model of tire wear quantity and difference as a function of road properties and vehicle dynamics is set up combined with vehicle-road coupling algorithm, and important parameters (e.g. vehicle speed, steering angle, braking force, and road feature) are analyzed to assess the tire wear quantity and difference feature when the vehicle is in unsteady condition. Results show that vehicle speed, braking force, and road surface feature have a significant impact to tire wear quantity and difference, the right rear exhibits a fluctuation and the tire wear quantity and difference between rear axle and the right side is obvious, and lay a strong foundation for tire road print analysis.

Particles formation due to the wear of tires and measures for the wear reduction: A review

“…Ho ¨pping et al 124 Tire simulator The wear of tires increases by appearance of wheels sliding during the braking process. Ma et al 117 Road tests In the case of accidental situation, which is characterized by emergency braking or change of the direction, the wear of tires increases. Kwak et al 122 Road tests and laboratory testing on a real vehicle During the vehicle driving in the curve, the wear of tires increases.…”

“…70 The same conclusions were also drawn by Li et al, 97 Du et al, 115 Kim and Lee, 89 Li et al, 98 and Cunha et al, 116 that is with the speed increment, the wear of tires rises, which is shown in Table 4. In the research conducted by Ma et al, 117 the authors determined that the greater wear of tires appears on the front axle in respect to the rear one. During the vehicle start, without sliding, the particles concentration was not measurable, while in the case of the racing start (start with wheels sliding), the particles emission from the wear of tires showed signification growth, 118 so and during the vehicle exploitation, in the case of wheels sliding this will cause the increased wear of tires.…”

The Analysis of Stone Trapping in Tire Tread for Various Road Conditions

“…In contrast, the equivalent elastic strain reaches to a greater value on a dry road for both cases. In general, it is understood that the dry road surface would generate more friction than the wet road surface and hence tire wear will be greater on a dry road [18]. Farroni et al [19] had also expressed that a dry road would results in a difficulty for the tire rubber to slip over the road surface which in turns leads to heat build-up in the tire.…”

“…Tire pressure, like other parameters, is a parameter that directly affects tire wear. Tire pressure varies depending on the load in-vehicle use and it is recommended to check frequently [2][3][4][5][6][7][8].…”
