摘　　要：研究带束层材料、带束层角度、三角胶高度和有无冠带层4种结构因素对轮胎模态和力传递特性的影响。结果表明:不同的带束层材料有不同的隔振性能;带束层角度与刚体模态频率呈正相关,但对空腔模态频率几乎无影响,带束层角度与轮胎力传递率呈正相关;三角胶高度与刚体模态频率呈正相关,但对空腔频率几乎无影响,三角胶高度与径向空腔及横向力传递率呈负相关;有无冠带层对轮胎模态频率影响较大,有冠带层轮胎比无冠带层轮胎径向模态频率大,且高阶模态更容易受其影响,而有无冠带层对横向刚体模态频率的影响呈负相关,有无冠带层与径向1阶和径向空腔力传递率呈正相关,与横向1阶力传递率呈负相关。The influence of belt material,belt angle,apex height,and crown ply on the tire modal and force transfer characteristics was studied.The results showed that different belt materials had different vibration isolation performances.The rigid body modal frequency and the tire force transfer rate were positively correlated with the belt angle,but the cavity modal frequency was not affected by it.Moreover,the rigid body modal frequency was positively correlated with the apex height,while the cavity frequency was not affected by the apex height.On the other hand,the radial cavity and the lateral force transfer rate were negatively correlated with the apex height.In addition,the tire modal frequency was significantly affected by the crown ply of the tires.The radial modal frequency of the tire with crown ply was higher than that of the tire without crown ply,and the higher-order modes were more susceptible to its impact,while the transverse rigid body modal frequency of the tire with crown ply was lower than that of the tire without crown ply.Besides,with crown ply,the first-order radial and the radial cavity force transfer rate were higher,but the first-order transverse force transfer rate was lower.
