| Abstract: |
| Taking a single tire groove as analysis object，the mathematical model of V-riblet distribution and hydroplaning model of tire were established.The hydroplaning performance of tire was analyzed by computational fluid dynamics method.The wall drag reduction rate of V-riblet structure and smooth structure was analyzed and compared by orthogonal experiment method，the V-riblet design parameters for the best drag reduction was obtained，and was introduced into the hydroplaning analysis for the bottom of tire longitudinal groove.The results showed that，V-riblet non-smooth structure could effectively reduce the drag coefficient of the groove wall，and anti-hydroplaning performance of tire could be improved. |
