摘要

轮胎动力学中许多具有挑战性的问题都与接触片内部发生的情况有关。重要的轮胎性能属性，如抓地力/摩擦、磨损和噪音都与接触贴片直接相关。Calspan及其技术合作伙伴Tekscan开发了一种新型传感器系统，可以测量轮胎在平带轮胎测试机上高速滚动时的接触压力。测量结果提供了在平坦路面上广泛的现实和相关操作条件下动态接触斑块压力(DCPP)的详细信息。比较了不同厂家尺寸和类型相近的三种轮胎的接触贴片行为。结果突出了轮胎设计决策的差异如何影响接触补丁行为，进而影响整体轮胎性能。提出并讨论了DCPP数据的其他应用。

Measurement of Contact Patch Pressure Behaviors in High-Speed Dynamic Conditions

ABSTRACT Many of the challenging problems in tire dynamics are related to what happens inside the contact patch. Important tire performance attributes such as grip/friction, wear, and noise are all directly related to the contact patch. Calspan and its technology partner Tekscan have developed a novel sensor system that measures the contact patch pressure of the tire as it is rolling at high speed on a flat-belt tire test machine. The measurement results provide detailed insights into the dynamic contact patch pressure (DCPP) in a wide range of realistic and relevant operating conditions on a flat roadway surface. The contact patch behaviors of three tires of similar size and type, but from different manufacturers, were compared. The results highlight how differences in tire design decisions influence the contact patch behavior and in turn the overall tire performance. Additional applications of the DCPP data are presented and discussed.

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.
