摘要

松弛长度的概念通常用于描述轮胎的瞬态响应。本文研究了瞬态响应在不同运行条件下的变化。通过在室内平带式轮胎试验机上测量瞬态操纵过程中的轮胎力和轮胎变形，使用一种新的优化方法，利用实验数据计算了各种轮胎刚度和相关的松弛长度。利用这种方法，已经确定了轮胎载荷、充气压力、速度和温度对这些刚度和松弛长度的影响。讨论了这些效应背后的机制，特别关注温度的影响。

Effects of Different Tire Operating Conditions on Transient Lateral Tire Response

The concept of the relaxation length is often used to describe a tire's transient response. This paper investigates how the transient response changes under different operating conditions. Through the measurement of tire forces and tire deformations during transient maneuvers performed on an indoor flat-belt tire test machine, experimental data were used to calculate various tire stiffnesses and the associated relaxation lengths using a novel method via optimization. With this methodology, the effects of tire load, inflation pressure, speed, and temperature on these stiffnesses and the relaxation length have been identified. The mechanisms behind these effects are discussed with a particular focus on the influence of temperature.

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.
