| 中文摘要: |
| 以205/55R16轿车子午线轮胎为例，建立轮胎三维有限元模型，对于同一胎体设计不同的胎面花纹，并采用主成分回归法建立轮胎滚动阻力和胎面与胎体间接触特性参数的线性回归方程，研究不同花纹胎面与胎体间接触特性参数对轮胎滚动阻力的影响。结果表明，第二长轴长度因数、第三长轴长度因数、接触因数和接触形状因数对轮胎滚动阻力影响较大，平均接触压力、第二长轴长度、第三长轴长度和接触长轴长度次之，最大接触压力和接触面积较小。 |
| 英文摘要: |
| By taking 205/55R 16 passenger car radial tire as an example，a three-dimensional finite element model of the tire was established. Different tread patterns were designed for the same carcass，and the linear regression equation between the tire rolling resistance and contact characteristic parameters between the tread and carcass was established by using the principal component regression method. The effect of contact characteristics on the tire rolling resistance was studied.The results showed that the length factor of the second long axle，length factor of the third long axle，contact factor and contact shape factor had significant impact on the tire rolling resistance，the average contact pressure，length of the second long axle，length of the third long axle and length of long contact axle also showed influence but with less significance，and the maximum contact pressure and contact area only had small influence. |
