| 中文摘要: |
| 以轮胎单个花纹沟作为分析对象，建立V形沟槽分布数学模型和轮胎水滑模型，运用计算流体力学方法对轮胎水滑性能进行分析。用正交试验法分析和对比V形沟槽结构与光滑结构的壁面减阻率，得到减阻效果最佳的V形沟槽设计参数，并引入轮胎纵向花纹沟槽底部进行水滑分析。结果表明，V形沟槽非光滑结构能有效降低轮胎花纹沟壁面阻力系数，提高轮胎的抗水滑性能。 |

| 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. |
