Abstract

ABSTRACT It is known that different weather conditions require a specific design to take into account the main mechanisms acting between the tire tread block and the road surface. When developing all-season tires, additional research is necessary to find the best solution considering various road conditions. This paper analyzes the influence of the inclination angle of tire tread blocks and the tire tread blocks siping design on different surfaces on the friction forces in lateral and longitudinal directions. The tests were conducted on the hybrid test rig Realistic Pattern Testing in Lab at the Institute for Dynamics and Vibration Research of the Leibniz University of Hanover with different single tread blocks. Tire tread blocks with different numbers of sipes were rotated with an angle between 0° to 90° in 15° increments. To simulate different road conditions, artificially produced ice and snow tracks and real road wet and dry asphalt were used. For a better understanding of the mechanisms, high-speed images of the same samples sliding over a wet glass track were taken from below. On the one hand, the measurement results and videos help to understand the influence of the inclination angle of a tread block sample on the friction process and show the different friction mechanisms on different surfaces and resulting forces in the two directions. On the other hand, the results show clear favorites for optimizing performance on individual surfaces.

不同路面(干、湿、雪、冰)上旋转胎面块样横向和纵向力传递的目标冲突

摘要:众所周知，不同的天气条件需要一个特定的设计，以考虑轮胎胎面块和路面之间的主要机制。在开发全季轮胎时，需要进行额外的研究，以找到考虑各种路况的最佳解决方案。分析了胎面块倾角和胎面块在不同表面上的四边形设计对轮胎横向和纵向摩擦力的影响。在汉诺威莱布尼茨大学动力学与振动研究所实验室的混合动力试验台上，对不同的单胎面块体进行了试验。不同数量的胎面块以15°的增量以0°到90°的角度旋转。为了模拟不同的道路条件，使用了人工制造的冰雪轨道和真实道路的湿沥青和干沥青。为了更好地了解其机理，从下方拍摄了相同样品在湿玻璃轨道上滑动的高速图像。一方面，测量结果和视频有助于了解胎面块试样倾角对摩擦过程的影响，展示不同表面上不同的摩擦机理和两个方向上产生的作用力。另一方面，结果显示了在单个表面上优化性能的明显偏好。

期刊介绍： Tire Science and Technology is the world"s leading technical journal dedicated to tires. The Editor publishes original contributions that address the development and application of experimental, analytical, or computational science in which the tire figures prominently. Review papers may also be published. The journal aims to assure its readers authoritative, critically reviewed articles and the authors accessibility of their work in the permanent literature. The journal is published quarterly by the Tire Society, Inc., an Ohio not-for-profit corporation whose objective is to increase and disseminate knowledge of the science and technology of tires.
