轮胎接地与干抓地性能关系研究

基于已有的10条205/55R16乘用车轮胎接地性态参数,具体包括总体接地区域、胎肩区域、过渡区域、中心区域4个分区,采用相关分析法和偏最小二乘回归法构建了接地性态参数与轮胎接地性能的关系,掌握了不同接地性态参数与轮胎干抓地能力的影响。研究结果可为高性能乘用车轮胎花纹设计提供指导作用。

Based on the tire contact grounding parameters of 10 tires of different brands of 205/55R16 passenger tires,which including shoulder region;transition region and central region.Using correlation analysis,the high correlated parameters about dr y grip were f iltered out.The relationship between grounding parameters and dr y grip was obtained by correlation analysis and partial least-squares regression method,the effects law of grounding parameters on dr y grip performance was also obtained.The results can be used to provide guidance for high performance passenger car.
