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。
In this study, the mathematical model of V-riblet distribution and hydroplaning model of tire were established by taking a single tire groove as analysis object,and 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 experimental method,and the V-riblet design parameters for the best drag reduction were obtained. The optimized V-riblet design was applied in the bottom of tire longitudinal groove and the hydroplaning performance was analyzed. The results showed that,V-riblet non-smooth structure effectively reduced the drag coefficient of the groove wall,and antihydroplaning performance of tire was improved.
