摘要/Abstract

摘要： 为从轮胎接地特性的角度来评价轮胎干湿抓地性能,以10条不同厂家生产的205/55R16型子午线轮胎作为研究对象,将轮胎总体接地区域划分为胎肩区、过渡区和中心区3个分区,通过轮胎接地试验获取其接地特性参数,并采用相关分析法筛选出与干湿抓地性能相关性较高的接地特性参数,再利用主成分法揭示了各接地参数与干湿抓地性能之间的定量关系。结果表明,基于轮胎接地特性参数表征干湿抓地性能的回归方程拟合效果良好,研究结果对高性能轮胎结构设计具有良好的指导作用。

Abstract: In order to evaluate the tire grip performance on both dry and wet roads from the angle of tire grounding characteristics, ten 205/55R16 tires from different manufacturers are studied. The overall footprint of tire is divided into three parts: shoulder region; transition region and central region, and tire grounding test is conducted to get the parameters of its grounding characteristics. Then a correlation analysis is performed to single out the high correlated grounding parameters and the quantitative relationships between grounding parameters and tire grip performance on both dry and wet grounds are revealed by using principal component analysis. The results show that good fitting results are achieved of the regression equations for the grip performance of tire on both dry and wet grounds characterized by tire grounding parameters, and the outcome of the research can play a good guiding role in the structural design of high-performance tires.

Key words: radial tire, tire grounding characteristics, dry and wet grounds, grip performance, correlation analysis, principal component analysis
