| 中文摘要: |
| 以Abaqus为平台，采用有限元法对245/70R16轮胎进行分析，研究负荷、外倾角和侧偏角对轮胎整体静力学与动力学性能、温度场与滚动阻力场分布的影响。结果表明：随着负荷的增大，轮胎整体的变形和接地面积增大，接地性能变差，肩部与胎圈部位的应变能密度增大，轮胎的横向刚度略有减小，纵向刚度和径向刚度略有增大，而旋转刚度明显增大，肩部和胎圈最高点的温度升高；随着外倾角的增大，轮胎的滚动温度场与滚动阻力场分布趋向于不对称，滚动阻力和滚动阻力系数均增大。 |
| 英文摘要: |
| Based on Abaqus，a finite element model of 245/70R16 tire was established to study the influence of load，camber angle and slip angle on the statics and dynamics performance，distribution of temperature and rolling resistance field.The results showed that，with the increase of load，the tire integral deformation and contact area increased which was unfavorable to the contact performance，the strain energy density of shoulder and bead area increased，the lateral stiffness of tire decreased slightly，the longitudinal stiffness and radial stiffness increased slightly，the rotational stiffness increased significantly，and the highest temperature of the shoulder and bead area increased.With the increase of camber angle，the distribution of rolling temperature and resistance field tended to be asymmetric，and the rolling resistance and rolling resistance coefficient increased. |
