| Abstract: |
| 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%. |
