摘要： A computer-implemented system and method are provided for vehicle tire performance monitoring, modeling, and feedback. Vehicle data comprising movement data and/or location data are collected for a vehicle and/or at least one tire associated with the vehicle. A current tire wear status is determined in real-time for the at least one tire, based at least in part on the collected data, various particular embodiments of which are disclosed herein. One or more tire performance characteristics, such as for example tire traction, replacement time and/or future tire wear, are predicted based at least in part on the determined tire wear status and the collected data. Real-time feedback is selectively provided based on the predicted one or more tire performance characteristics and/or determined current tire wear status. The feedback may include alerts to an operator or fleet management personnel, or may take the form of automated control invention.

摘要： An apparatus and method are disclosed for modeling at least a portion of a rolling tire (200). A finite element model of at least a portion of a tire (200) rolling against a tire contacting surface (202, 506, 602) is input into a finite element analysis system (100). The system executed instructions that result in the application of a constant force to the model tire (200) or portion thereof by the tire contacting surface (202, 506, 602). The application of force control boundary conditions, as opposed to displacement control, provides significant benefit in terms of computational time of the finite element analysis solution. A finite element analysis simulation of the model against the tire contacting surface (202, 506, 602) is performed while maintaining the force on the model tire (200). Alternatively, a camber (γ) is also applied to the tire and maintained throughout the simulation.
摘要翻译： 公开了一种用于模拟滚动轮胎（200）的至少一部分的设备和方法。 相对于轮胎接触表面（202,506,602）滚动的轮胎（200）的至少一部分的有限元模型被输入到有限元分析系统（100）中。 该系统执行导致由轮胎接触表面（202,506,602）对模型轮胎（200）或其部分施加恒定力的指令。 力控制边界条件的应用与位移控制相反，在有限元分析解决方案的计算时间方面提供了显着的益处。 在维持模型轮胎（200）上的力的同时执行抵抗轮胎接触表面（202,506,602）的模型的有限元分析模拟。 或者，也将外倾角（γ）施加到轮胎并在整个模拟过程中保持。

摘要： A tire (100) comprises a first side (120a) and a second side (120b) defining a counterclockwise first rotation direction (D1) and a clockwise second rotation direction (D2), respectively, and a circumferential tread (130) disposed about the tire (100) and including a plurality of tread elements (800; 900; 1000; 1200) with each of the plurality of tread elements (800; 900; 1000; 1200) having a plurality of sipes (830; 930; 1030; 1240) disposed therein. The plurality of sipes (830; 930; 1030; 1240) causes the tire (100) to exhibit a first tire performance when the tire is rotated in the first rotation direction (D1) and a different second tire performance when the tire (100) is rotated in the second rotation direction (D2). First indicia (150a) and second indicia (150b) are disposed on the first side (120a) and the second side (120b), respectively, and include an indicator designating the first rotation direction (D1) as a front tire rotation direction and the second rotation direction (D2) as a rear tire rotation direction.

The geometry of the plurality of sipes (830; 930; 1030; 1240) causes the tire (100) to exhibit a first tire performance when the tire is rotated in the first rotation direction (D1) and a second tire performance when the tire (100) is rotated in the second rotation direction (D2).
