| 中文摘要: |
| 通过垂直负荷分布修正和滑动摩擦因数参数化，建立轮胎纵向力模型，利用其对轮胎纵向力特性进行分析，并研究各因素对轮胎纵向力的影响。结果表明，随着静摩擦因数的增大，接地胎面完全滑移的滑移率增大，滑移力（Fsx）和附着力（Fax）增大；纵向刚度主要影响峰值前的纵向合力，随着轮胎纵向刚度和接地印痕长度的增大，接地胎面完全滑移的滑移率减小，Fax减小，Fsx增大。 |
| 英文摘要: |
| A new tire model for longitudinal force was established by modifying the distribution of normal load and parameterizing the sliding friction coefficient.The model was used to analyze the longitudinal force charateristics of tire and investigate the influence of various factors on the longitudinal force of tire.The results showed that the sliding ratio of ground-contact tread,the sliding force (Fsx) and the adhesion force (Fax) increased as the static friction coefficient increased;the longitudinal stiffness mainly had influence on the joint longitudinal forces before the peak value;and the sliding ratio of ground-contact tread and Fax decreased,and Fsx increased as the longitudinal stiffness and the length of foot-print increased. |
