摘要: 为研究轮胎接地性态对轮胎噪声、滚动阻力的影响规律,以型号为205/55R16的PCR轮胎作为研究对象,通过轮胎接地试验获取10个不同厂家生产的PCR轮胎的接地性态参数,对接地印痕进行细化分区以提取各分区接地性态参数,利用数值分析方法研究各分区接地性态参数与噪声、滚动阻力之间的定性、定量关系。结果表明:胎肩区域、过渡区域、中心区域对轮胎噪声值有较大影响;接地印痕长宽比、胎肩区域、过渡区域对轮胎滚动阻力影响较大;外内胎肩内侧长之比、外胎肩长、外过渡长为轮胎噪声、滚动阻力共同影响参数,且与轮胎噪声值、滚动阻力之间均呈负相关关系。利用主成分分析法建立了接地性态参数与轮胎噪声值、滚动阻力间的回归方程,拟合效果良好。研究结果为低噪声、低滚动阻力高性能绿色轮胎设计提供了理论指导。

Abstract: In order to study the grounding characteristics' influence on noise and rolling resistance(RR), taking 10 different 205/55R16 tires as the object of study. Grounding characteristics parameters are obtained through tire grounding test, the footprints are refined and divided,grounding parameters of each subarea are extracted. The qualitative and quantitative relationship of grounding parameters, noise and RR are studied by numerical analysis method. The results show that the shoulder region, transition region and central region have great influence on noise; Overall aspect ratio, shoulder region and transition region have great influence on RR; Inside length of outside shoulder, the length of outside shoulder and outside transition region effect tire noise and RR performance at same time. Noise and RR are negatively correlated with common influence parameters. Regression equation of grounding characteristics parameters with noise and RR are established by the principal component analysis method. The predictive value and actual value have good fitting results. The research results provide theoretical guidance for the design of low-noise and low RR green high-performance tires.

Key words: grounding characteristics, low noise, low rolling resistance, numerical analysis, PCR tires
