摘　　要：以205/55 R16型号轮胎为研究对象,基于Abaqus CEL流固耦合方法构建轮胎滑水有限元模型。将模拟得到的轮胎垂直刚度与实验数据进行对比,验证轮胎模型可靠性的前提下,优化欧拉域,更好地捕捉并分析轮胎滑水时水流印迹特征。结合NASA经验公式评估模拟得到的临界滑水速度,验证轮胎滑水模型可靠性,分析不同充气压力和水膜厚度对轮胎临界滑水速度的影响。通过引入V型横向花纹和增加F1 Nose结构优化轮胎花纹结构,验证花纹沟槽子模型优化合理性,对比优化前、后轮胎临界滑水速度和水流压力。结果表明:此优化方法能有效提高轮胎的滑水性能。In this paper,the 205/55 R16 tire is used as the research object.Based on the Abaqus CEL fluid-structure coupling method,the finite element model of tire hydroplaning is built.The tire vertical stiffness generated from the simulation is compared with the experimental data.While validating the reliability of the tire model,the optimized Eulerian domain helps better capture and analyze the water flow characteristics during tire hydroplaning.The hydroplaning critical velocity generated by NASA empirical equations is employed to verify the reliability of the tire hydroplaning model.The impacts of different inflation pressure and water film thickness on the tire hydroplaning performance are analyzed.The tire tread structure is optimized by introducing a V-shaped transverse tread pattern and adding an F1 Nose structure.The validity of the optimized tread groove sub-model is verified,and then the hydroplaning critical velocity and water flow pressure of the tire before and after the optimization are compared.Results show our optimized method effectively improves tires’hydroplaning performances.
