摘　　要：为研究胎面接地变形特性与轮胎噪声和抓地性能的关联关系,选取10条型号相同但胎面花纹结构不同的PCR轮胎作为研究对象,通过VIC-3D全场非接触应变测量系统获得了试验轮胎额定载荷下的接地变形特性参数,随后采用相关性分析法筛选出与轮胎噪声、抓地性能呈高相关性的接地变形特性参数,并借助ISIGHT软件构建了表征轮胎噪声和抓地性能的Kriging近似模型。结果表明,轮胎的噪声性能主要与胎面径向变形量呈高正相关性;抓地性能主要与胎面X方向应变呈高正相关性,与胎面Y方向应变呈高负相关性。对轮胎噪声性能影响较大的胎面接地子区域为胎面中心区,其次为外过渡区、内过渡区、外胎肩区和内胎间区,权重值依次为0.843、0.576、0.522、0.149和0.087;对轮胎抓地性能影响较大的胎面接地子区域为外胎肩区,其次为外过渡区、内过渡区、中心区和内胎肩区,权重值依次为0.587、0.487、0.354、0.311和0.286。In order to study the influence of tread ground deformation parameters on tire noise and grip performance, 10 PCR tires with the same type but different tread patterns were selected as the research objects. The deformation characteristic parameters of tire contact area under rated load were obtained through VIC-3D full field non-contact strain test. Through the correlation analysis, the ground deformation characteristic parameters with high correlation with tire noise and grip performance were selected, and a Kriging approximate model was constructed by ISIGHT software to quantitatively analyze the relationship between high correlation parameters and performance. The results showed that the noise performance of the tire had a high positive correlation with the radial deformation of the tread, and the grip performance was mainly positively correlated with the x-direction strain and was mainly negatively correlated with the y-direction strain. The tread area which had a greater impact on the tire noise performance was the central area, followed by the outer transition area, inner transition area, outer shoulder area and inner tire area which the weight values were 0.843, 0.576, 0.522, 0.149 and 0.087 respectively;the tread area with greater impact on the tire grip performance was the outer shoulder area, followed by the outer transition area, inner transition area, central area and inner shoulder area which the weight values were 0.587, 0.487, 0.354, 0.311 and 0.286 respectively.
