| 中文摘要: |
| 针对205/55R16轿车子午线轮胎，建立三维花纹有限元模型，采用回归分析的方法，研究花纹设计参数与滚动阻力的关系。选取纵沟深度、纵沟宽度、横沟深度和横沟宽度作为设计参数，采用响应面设计方法进行方案设计。结果表明，4个设计参数对滚动阻力的影响程度从大到小依次为纵沟宽度、纵沟深度、横沟宽度、横沟深度。利用最小二乘法拟合花纹设计参数与滚动阻力的关系式，并且通过优化求解得到优化花纹设计参数。花纹设计参数优化后轮胎的滚动阻力比花纹设计参数优化前降低3.89%。 |

| A 3D pattern FEA model of 205/55R16 PCR tire was established. The regression analysis was used to analyze the relationship between the tread pattern design parameters and rolling resistance. The depth of vertical groove and horizontal groove, and the width of vertical groove and transverse groove were selected as the design parameters，and schemes were designed by response surface analysis method. The results showed that the influence degree of four design parameters on rolling resistance decreased in the order of: vertical groove width，vertical groove depth，horizontal groove width，and horizontal groove depth. The relationship formula between tread pattern design parameters and rolling resistance was fitted by the least squares method，which was used to predict and optimize the tire pattern design parameters. Compared the tire with original pattern design parameters，the rolling resistance of the tire with the optimized pattern design parameters was reduced by 3.89%. |
